Risk Ingredients

Manufactured By
Manufactured at company owned facility in Minnesota.


  • Ingredients are sourced from USDA or FDA inspected facilities.
  • Contains multiple animal proteins – chicken, pork, herring.
  • The mineral listings read to be chelated or proteinated (for better mineral absorption).


  • Contains DL-Methionine, a synthetic amino acid.
  • This food does include probiotics (friendly bacteria that benefits the intestinal system and in turn the immune system of the pet), however they are not listed in the Guaranteed Analysis (no company guarantee bacteria is viable).


Learn More

This pet food contains a synthetic amino acid DL-Methionine. Click Here to read more about this supplement.

The sodium selenite ingredient in this cat food is not noted under minus as it would be in a dog food. The reason: the safer form of delivering selenium to the pet food, selenium yeast, is not yet approved for use in cat foods by the FDA. This manufacturer is using sodium selenite because it is the only option for this supplement. Click Here to read more about selenium.


To explain the rating – only the first five ingredients – the majority of the food – are rated and listed in bold type. Grey Font ingredients imply ingredients providing pets little to no nutrition, and Red Font ingredients are Red Flag ingredients that are potentially dangerous to pets. Quality ingredients are listed in bold black font. Five quality ingredients gives the pet food a five Paw Print rating. Four quality ingredients gives the pet food a four Paw Print rating, and so forth. Four Paw Prints is the highest rating possible for a canned pet food. Do not rely on the paw print rating alone; read the Plus/Minus information and manufacturer information at the top of each page.

  1. Dianna says:

    Thank you for this review of Young Again cat food. I have been feeding my 17 cats their other low carb cat food, and have recently switched to their zero carb food. I have no diabetic cats and want to keep it that way. The older ones do indeed act “young again” at times, it is funny to watch the play. I am very happy with this food. BTW, I am diabetic and eat a zero carb diet myself. Thanks again for what I consider a good review.

  2. Linda Muir says:

    Do I remember that you, Susan, recommended against feeding dry kibble of any kind. Somewhere on one of your pages, or your book, you said feed your cat canned food or wet food not kibble.

    Yet you are giving a thumbs up to this food, which is kibble. I am confused!

    • Susan Thixton says:

      I don’t feed my own pets kibble (cats or dogs) but I don’t make that ‘recommendation’ to others – choosing a pet food, even choosing a style of feeding (can, kibble, fresh, raw) is a very personal decision. There are just too many variables for a one size fits all pet food. What works for me and my pets doesn’t necessarily work for you and your pets. With Petsumer, ratings are based on the first five ingredients and if they provide any nutrition. The rating system doesn’t make judgments if the food is can, kibble, or raw – it is a very simple system. And it rates the same way for any style of food. The Plus/Minus of Petsumer and the Learn More gives petsumers additional information to base their pet food purchasing decisions on.
      And also – the rating is not a ‘thumbs up’ from me. It’s just a rating based on those first five ingredients (nutrition providing ingredients or not).

      • Tina says:

        This is why I come to your page first to read about pet foods. Yours is a educated, unbiased opinion. You never make any one feel horrible for NOT feeding their pets the same way you feed yours. Thank you for that.

  3. Mirel says:

    I bought their food once but was scared off by the yeast extract. Do you happen to know if it is safe?

    • Young Again company response: Yeast extract in the food industry is a flavor enhancer used to replace MSG. Reports are that it is not much better than the original MSG. Young Again had yeast extract on our label which is not a flavor enhancer and in no way comparable to the flavor enhancer yeast extract/MSG used in the human food industry. Our term yeast extract was meant to describe the process used to extract individual nucleotides from whole brewer’s yeast; hence we used the term yeast extract. Nucleotides combine with stomach acid to form nucleic acids which are absorbed by the body and intern form the building blocks of every cell in the body. It is very beneficial for every organism to have access to additional nucleotides so that they can rapidly build any cell they need. To prevent confusion and be more accurate and comply with FDA regulations, our labels are being reprinted to list only brewer’s yeast.

    Are foods ever re reviewed on petsumer? Like if a company/food was reviewed in 2012, would it be reviewed again later(say the following year) to see if anything has changed?

  5. sheila b says:

    Thank you! Buying a subscription now

  6. sheila b says:

    Just fyi, I called nature’s variety twice last week to ask about their rabbits being from china. They stated that they get their rabbits from France and that nothing is shipped to China for any kind of processing. They also stated that nothing comes from china. How well do you think I can take their word for it? They said it had been awhile since they used china

    • Susan Thixton says:

      Until we can get the certification program going (which would certify human grade and country of origin of all ingredients) – consumers have no choice but to trust manufacturers. There is no guarantee (but we are going to make one happen soon).

  7. sheila b says:

    One last question. Are the reviews dated? I can’t seem to find when the reviews were written.

    • Susan Thixton says:

      No – they aren’t dated. But I can tell you all of the reviews in Petsumer have been done within the last year. We moved Petsumer to a WordPress format a year ago.

  8. Alexandra says:

    I started feeding my Border Collies Farmina N&D and was so happy I started the cats on the food as well.

    Nothing can compare to these foods, nothing. I have used everything and these are the best foods for dogs and cats.

    • Dave says:

      The Farmina N&D boar & apple’s third ingredient is potato. Cats are obligate carnivores and cannot process starches.

  9. Marc Jay says:

    Young Again cat food is no cure for diabetes nor a substitute for insulin, as their product descriptions imply. I put my diabetic cat on their Zero Carb food, based on the claims they make of getting cats back to normal glucose levels, and all the money we’ll save on insulin as a result.

    Well, the food had no effect whatsoever on my cat’s diabetes, which continued to grow worse, until he ended up in critical condition. His insulin dosage wasn’t sufficient to keep glucose in healthy range, and this food was of no help. Furthermore, my vet informed me that all-protein and high-protein diets bring their own set of risks, as they are harder on the kidneys, and kidney disease is another common problem in aging cats.

    So if you want to believe it will *prevent* diabetes in your currently healthy cats, and hope that it will not induce kidney disease in them, sure go for it. Keeping your cat away from high carbs is a good idea.

    The trick to selling more product, is that since your cat doesn’t have diabetes yet, you’ll have no evidence that the food *isn’t* working, so you’ll continue buying it, much like you continue to take Vitamin B or garlic, as it may prevent heart attacks, and since you haven’t had a heart attack yet, it must be working.

    But don’t buy Young Again thinking it will help or cure your already diabetic cat. It will not. My diabetic cat is alive and healthy now, thanks to the correct insulin dosage, and a diabetic food from the vet. He went from near death ketoacidosis while on a Young Again diet, to pure bliss, running and playing like a kitten.

    • Young Again company response: It is always unfortunate when a client reads more into a food that they should. We would never say that any food could be a replacement for insulin. Diabetes cannot be cured; however a cat can go into remission. Remission occurs when the pancreas can produce enough insulin to maintain the BG in the normal range. If your cat’s pancreas is compromised and can’t produce enough insulin, then your cat has become diabetic. However a compromised pancreas may still have some level of functionality and by reducing the glycemic index of the food (removing starch/carbs) the pancreas may be able to function well enough to maintain proper BG and therefore the cat can go into remission ( no need for insulin). Sometimes it takes time for a cats pancreas to settle down and remission can take months to occur and sometimes your cat will remain diabetic and will always require insulin (like Marc’s cat). Young Again Zero carb is not a replacement for insulin. If your cat still has high BG levels while eating our food you must treat your cat with insulin. The Zero carb formula will produce very high rates of remission (up to 85%) but, remission can take anywhere from days to many months to accomplish and some cat will never go into remission. Marc is currently feeding a prescription diabetic food and as far as I’m aware, they all contain an abundance of carbohydrates. The reason his cat is doing better is because he is now giving the cat the proper dose of insulin. If he had given the proper insulin dose while feeding Young Again, he would have had the same acceptable results. However, because there are no carbs in the Zero Carb food he would probably need less insulin to maintain his cat’s BG and he would save money. You want to give the lowest dose of insulin that is necessary to maintain proper BG, so that you lessen the possibility of the diabetic cat developing insulin resistance.

      If you want to help prevent your cat from getting diabetes then feed them as nature intended, as an obligate carnivore. Do not feed blueberries, veggies, grains, plant proteins and keep their total dietary starch/carb content below 6%. If you do this your cat will not get fat and their chance of developing diabetes will be greatly reduced. As a side note I’m going to still take my garlic, magnesium, vitamin D3 and my omega 3 fish oil because they have been proven to be beneficial in combating heart disease.

      Some vets still believe that high levels of protein are harmful to a cat with kidney disease (CRD). This may be true for plant proteins, but is not true for animal proteins. The problem is high levels of phosphorus not protein. CRD cats do very well on our Mature Health foods because they are low (0.50%) in phosphorus and only use animal protein. Phosphorus not animal protein has been proven to be harmful to CRD cats.

  10. Simmons says:

    I get my food at a only natural place and was told rosemary extract is toxic to cats, but see it on the list of ingredients. Upon further research on the internet i read the same thing but seeing it here I am not sure now. Please help explain thanks!

  11. Dave says:

    I have two kittens under 1 year. It seems that most of their customers are using the zero carb formula to aid with diabetes issues. This was not my issue. I tried in vain for almost 3 month to transition my two kittens over from Orijen [which is a high-quality food, but higher in carbs (~18%)]. I tried free-feeding, which was a disaster, then controlled amounts using an auto-feeder. One cat did fine, but the other had nothing but loose stool issues. My concern with the food came because either she was allergic to perhaps the pork ingredient, which is the major source of protein in the product, or, most likely, in order to get the amount of protein needed for a growing kitten, I needed to give her more than she could tolerate. When I fed her what was recommended she lost weight. When I increased her feeding amount, then she could not digest the amount properly.

    After several months of trying, I went back to Orijen. Since then both cats have been perfectly fine. Perhaps after a year or so (as the breed is a larger one (Pixie-Bob), they tend to grow for several years), and they have filled out and are no longer needing to eat a quantity needed for growth I’ll switch back.

    • Young Again company response to the above concern: Stool issues while converting many cats and especially kittens, has always been the most frequent customer service call we take at Young Again. We always suspected it was related to the type and content of the dietary fiber in the food and the fact that cats consume more of the high starch/carb diet, in comparison to a carnivore diet. We know that cats in general over consume because 60% of all cats are overweight and most cats are still consuming high carb foods. We just concluded a multiple year study and have found that psyllium fiber is perfect for cats. Psyllium fiber and tomato pomace are the only dietary fibers we currently ad to all of our foods. Stool issues are no longer an issue and we no longer receive customer service calls related to stool issues. It has been an amazing development.

      • Dave says:

        Now that my kittens have “graduated” past the 1-year mark I have “partially” been able to transition them to Young Adult 50/22. One is doing quite well on YA alonel, however the other one has not been quite as successful. Even after 2 months of using YA, she still had runny, stinky stool, even when feeding her the recommended amount and below. In fact, if I fed them the recommended amount she became very thin…even the vet said she became way too thin.

        I have found that mixing—and I know you don’t recommend that—YA with 20% low carb 50/22 Evo her stool became normal, and I’m able to feed them a diet that keeps both of them looking trim but not scrawny, which is about 45 gm/kg per day. This, by the way, is the amount recommended by a number of well-respected vets, including Mark Peterson, who performed at least a similar study with adult cats on a young mouse diet.

        Perhaps in time I will be able to get them onto pure YA, however at the moment I’m going to stick with what works.

  12. Tina says:

    I feed my 14 cats Zero Carb. None of them are diabetic or have any health issues. I did it because of grain free and starch part. Mine are all middle aged, 7 to 10 years old, In a couple years I will probably switch to their Zero Carb for senior cats. My cats seem to be doing really good. No bathroom issues or any thing. I can free feed this one too and my fatty cat is doing great. I think he’s actually lost weight. My other cats were already at their perfect weight and are maintaining it beautifully. I had tried this food once before but stopped because it does make the cat box stink in the first couple weeks and I thought it was them having a bad reaction. Now I have been patient this time and see it was just transitioning. Their poops are small and dry really fast so it’s easy to clean my litter boxes still. I was feeding The Honest Kitchen, which I LOVE, but that was costing me $330 a month for 14 cats. I just can’t afford that. This stuff is only $129 for a 25# bag and I keep it in a little apartment fridge to keep it fresh for the whole month and half that it lasts. I have a German Shepherd that I’m thinking about trying their dog food one. He has allergies. I am looking for reviews of the dog food first though.

    • Young Again company response: Thank you for using our food. Just a quick recommendation. None of your cats are diabetic or pre-diabetic; therefor any of the other Young Again foods that contain less than 6% starch/carbs will work for your cats. Since all your cats are mature I would highly recommend the Young Again Mature Health since it is lower in minerals, especially phosphorus which is critical in maintaining kidney health as your cat’s age. Your cats are considered mature as soon as they are done growing bone. For most cats that will be at about 2 years of age. However, for giant breeds like the Maine Coon, it may be as long as 5 years. Please consult your veterinarian or breeder if you are unsure if your cat has reached adulthood. It should also be noted that most cats develop urinary crystals or uroliths between the ages of 2 and 10 years of age. Most people normally do not consider using the lower mineral/mature formulas until their cat is about 10 years of age. For most cats you would be far better off if you started feeding the Mature Health at 2 years. Feeding excess minerals to cats will probably be shown to be one of the leading factors contributing to the formation of crystals and uroliths. In addition any time a cat is overweight she is not only consuming excess calories/food, but also excess minerals.

  13. Giani says:

    Will a cat initially gain weight when beginning free feed of YG? I have a 3 year old spayed female who is not 12 lbs. She was 13 lbs and I have her on a diet with just canned food but need to supplement with a quality dry food soon. She had bouts of UTI which the vet put her on different dry prescription foods which were very high in carbs. Also, the commercial foods are awful that are called urinary foods which would just make her weight go up and all the work I put in is lost.

  14. Jan Bradish says:

    Mar. 11, 2016 I am dating my response so it’s seen as current. My cats will no longer eat Young Again Zero Carb or Zerp Carb Mature since their recipe change, after being successfully on this food for 2 years. They have lost substantial weight over the past month during the period of trying to transition them to these new recipes. Tomato Pomace is a recent change from previously using phyllium as the fiber content. We notice a distinctly bitter smell when we opened the first bag. One of my cats is diabetic and went into remission 3 years ago when we started using Young Again Zero Carb. Now I am back to transitioning our 14 year old cats off Young Again because they are not doing well. Besides the lost weight, other diabetic symptoms are returning both cats (diabetic and non-diabetic), including excessive drinking and huge urine balls in the litter pan. I am very disappointed in this change Young Again has made in their Zero Carb Cat Food, which they explained was done because some cats were overeating the recipe containing psyllium for fiber. It was perfect for us, but now they have ruined a good thing for our cats and I am worried about the diabetic cat’s health. He has never been on insulin and is no longer, I’m afraid, in remission.

  15. Sarah says:

    I’m currently awaiting my order of the zero formula for my overweight pre diabetic cat. She has bouts of flutd and I am hoping this helps with this. She loved the sample so I am hoping this food helps alot of her issues stay at bay. Are all of the formulas good for urinary issues? Thanks!

  16. J A Riggs says:

    BEWARE ZERO CARB CAT FOOD!! I started feeding this to 4 cats since one was diabetic. Ok’d by vet. HIGH PROTEIN =HIGH PHOSPHORUS and other minerals. Yes, glucose level improved, but 10-yr-old cat euthanized for kidney disease less than one year after diagnoses, and 9 months on Young Again Zero Carb cat food.

    Newly adopted diabetic cat is off insulin on scheduled meals of Iams canned food only.

    • Sarah says:

      That’s not why your cat got kidney disease. 90% of cats develope it from genes animal protein isn’t the protein they can’t break down its plant protein. Kidney disease can get worse in some cats rather than others. Food doesn’t really make the difference. So that isn’t going to stop me from feeding the food.
