Zero Mature Health, Reviews

This food has gone above and beyond for my cats, especially my most senior cat. He was just diagnosed with very early stage kidney disease and early hyperthyroidism, but since I've been feeding them this food even before he was diagnosed since I adopted him a couple months ago, he has great phosphorous levels and he is building healthy muscle mass back! When I brought him home he couldn't even jump on the couch or anything, now he can jump all the way up on our really high bed (we have stairs for him anyway, but he can do it!) and he loves running around the house and jumping onto the couch for snuggles. I had to give them their old food for a few days last month (my fault, I forgot to put in my order) and all three cats turned sluggish and didn't want to do anything. As soon as they got their Young Again food back they were back to their normal energetic antics! This food gives them energy, top quality nutrients they need, and supports a very healthy lifestyle for my kitties. Plus, they love it!! We're on bottomless bag now and we're never going back! 

***While Aeriel has had wonderful success with our Zero Mature product due to the low phosphorous content,  we would suggest our LID Zero Mature for her cats.  Our LID Zero Mature contains only Hydrolyzed pork (no Chicken) as the protein source and has low phosphorous as well.  The hyrdrolyzed meat protein source is very easy for kidneys to process, making it the best for kidney cats and their adult housemates.

In December 2024, my BFF who has a cat rescue specializing in elderly cats who are doomed to be euthanized at the shelter, recommended this food. Our two cats are young at just five years old so I reached out to Young Again to find out what the best food would be for them. To my delight the President of the company responded right away with the following email: Hi Libby, Our Zero Mature Health would be s great choice. No carbs and low in phosphorus to help protect long term kidney health. Michael J.

I would probably give more than 5 stars, if it was possible. My 12 year old cat was diagnosed as diabetic a year ago. The vet started him on insulin and I was checking his blood sugar levels at home. Within 2 weeks of changing his diet to Young Again Zero Mature along with low carb wet food, he went into complete remission and came off the insulin. He hasn't had a high blood sugar reading in over a year. I just check it once a month for good measure, and it stays around 100. I discovered this cat food while researching safe dry foods, for diabetic cats, because Taffy is a kibble addict. He also likes variety in his life and gets bored with foods very easily, so he gets his Young Again Zero Mature at night to graze on and a variety of low carb wet foods throughout the day. He went from 19 pounds to 16 and now 14. The vet wants him down to 12, so we're getting there. He is so much more active since eating Young Again Zero Mature. Thank you so much for saving our boy from diabetes and insulin.

I started off with Zero and have switched to Zero Mature. Have been eating this food since early 2024. I have two cats at home and they easily transitioned. The best part is my diabetic cat went into remission within a few months and has stayed that way for almost a year now! I am saving money with no insulin or needles and both cats are healthy. My vet was in shock. Highly recommend!!

As the owner of a diabetic cat who has been on Bexacat for the past 6 months, I was hesitant to try a new cat food. However, I'm so glad I took a chance on this brand. I've only been feeding it to my cat for 2.5 weeks, and I've already seen an impressive 5 point decrease in his blood sugar numbers. What really sets this company apart is their exceptional customer service. When I reached out with questions about using this food alongside Bexacat, the president of the company personally responded to address all of my concerns. They were incredibly knowledgeable, transparent, and went above and beyond to ensure I felt confident in transitioning my cat to this new diet. Honestly, I wish I had found this cat food sooner, before starting Bexacat. Based on the rapid improvements I'm seeing, I'm hopeful my cat may even be able to go into remission and eventually stop the medication. If that happens, you can bet I'll be leaving an even more glowing review. This is simply the best cat food for diabetic felines that I've come across. The customer service is unparalleled, the quality of the ingredients is top-notch, and the results speak for themselves. I give this product my highest possible recommendation. (Client has fed both the Zero and the Zero Mature during the time of this review so it has been posted in both product reviews.)

I was very wary of trying this and debating for a whole year before caving and giving it a try. I called and asked all of my questions and felt reassured. Fast forward to a year later, my cat is STILL in remission and had great numbers on our last visit.

We are in the process of switching all four of our cats to your food...not just the one with diabetes (who is now in remission - THANK YOU!!). Thank you so much for saving our little furball from multiple pokes a day :). I am so blissfully happy that he's better!

Billy Pedersen, 8/5/2024

Both of my senior cats are in remission (diabetes) with just this food alone. Please do not hesitate to try it. It's saving my cats lives. They both also have asthma and are needing to be on steroids long term. So being in diabetic remission is so important. Thanks so much Young Again !!

Laurel Baber, 6/18/2024

My cats blood work was great for his age of 14 and I’m sure your food and plenty of filtered water helped with that, plus no more urinary crystals or bladder stones, thank God. His vet was surprised that his kidney function was normal so I told her about YA.

My 14 year old female Chaos was diagnosed with diabetes about a year ago. We struggled with insulin shots and low carb vet diets with no luck and lots of weight loss. She is a due hard dry food mirror and just wouldn't eat the wet no matter what i mixed in our sprinkled on it. At the time I was also having food and medication issues with my 15 year old tuxedo Zak and 14 year old tabby Weiser, who both suffer with thyroid disease and CKD. One day I'd had enough and decided there had to be a better way, so I started googling and found young again. I was mildly hopeful at first and spoke to my vet, she said she could not recommend the food because it didn't have the credentials that she felt were necessary...I basically said to heck with her opinion and ordered the food. I am so happy I did, my diabetic (to my vet's surprise) is in full remission! And ofcourse I would not shut up to everyone in the vets office about how Young Again cat food works miracle. In addition my other (3) cats are doing well with the food (the 3rd is Dean the long haired calico) he was always getting constipated... but not anymore, he has been very regular since starting on young again which makes him and me very happy :) so overall hands down this is the absolute best cat food out there. I talk about it so much that 2 of my coworkers have started their cats on it and the one with the diabetic cat is also now in full remission! I love this stuff ❤️

I have been using your Zero Mature food since my diabetic cat was diagnosed 13 years ago. He is now gone. He had been diet controlled with your food for years and died of old age. I kept using the Zero Mature food because my cats were all doing so well on it. I just got back from the vet for a wellness check for Trout, my fifteen year old sassy tortie. He was absolutely amazed at how good she's doing and how much muscle she still has at her senior age. He asked what I was feeding her. I told him about your food and how I switch to it for Rocky and after he died of old age, I just kept feeding it. He said it must be amazing because Trout is doing so well. He asked where I get it. She is going back in a couple of weeks for a dental. Do you have some literature about your food and company that I could bring to that visit to show him. I don't usually advertise companies, but your food is truly amazing. I reminded him that when Rocky had to be hospitalized, they fed him their RX vet diabetic formula and his glucose shot up to 700. All 6 of my cats continue to do great on the Zero Mature and I'd like to share any information you have with my veterinarian.

Like others, I found Young Again cat food while searching for a reduced phosphorous option for a senior cat with early CKD. Sassy is 15 at the youngest (I found her on the street so her age is a guess) and while she has always been healthy and well hydrated, age does catch up with all animals eventually and she was diagnosed with very mild, early-onset CKD about a year ago. She also has hyperthyroidism, and between these two conditions she was rapidly losing weight, even with medication. Since switching her wet food to a low phosphorus option and her dry food to Young Again Zero Mature, she is back to a healthy weight and her conditions have not progressed at all. She loves the taste and it's quite affordable for the quantity and quality. No complaints. Thanks for making a great product and keeping my little buddy healthy!

This cat food has made a big difference in my 17 year old cats. Both have chronic kidney disease. They both eat this food when they will not eat a lot of other foods. We feed them wet food and this dry food. It has made them interested in eating again. I can even give them this food as treats. They really like it. And it’s good for them. It is wonderful to see them happier and more playful and interested in eating again. Thank you for making this cat food. I highly recommend it.

I always recommend YA, especially when people find out they have a kitty with Diabetes. I know that serving YA Diabetic food to our boys when they were diagnosed helped save their lives, and it helped get that disease under control and into remission for them. We had 3 cats that were diabetic.

I have to express my deepest and sincerest thanks. About a year and a half ago my cat was diagnosed with diabetes while undergoing treatment for a stone in his bladder. I struggled maintaining his blood sugar levels, nothing seemed to work he was up to 7 ccs of insulin twice a day and barely dropping below 300. Then I had a couple scare incidents where he was dropping below 50. I realized that those were days that he was eating less. He was on a special food for urinary crystals, And I learned that was 27% carbs. First, I switched him to a much lower carb kibble, (he abhors wet food and will starve himself for 3 days rather than eat it, and then only enough to curb his hunger) and that helped, but your kibble has really brought him back to life. Since he has been on your Zero Mature recipe, it is like my 10-year-old little man is ... well ... Young again! I spent over a year barely seeing him and him having difficulty even walking developing ataxia in his hind legs. Now he is back to annoying me at all hours, running around the house, jumping up on the sofa and tables, I might have to get him a cat tree again soon! Thank you so much for everything that you do! Thank you so much for bringing life back to my baby boy!

Our cat Colby was diagnosed with diabetes. He was placed on insulin injections and was also having severe diabetic neuropathy. He could barely walk on his hind legs. The vet recommended a zero carb diet of wet foods. He was so picky! No matter what we tried he wouldn’t touch it. I found this thru an internet search for dry food. He loves it! He’s been on it about 3 weeks now and absolutely loves it. No more pain meds, insulin down to 1 IU. He’s acting like he did when he was half this age. Thanks again YA!

My male cat Smokey (Mo-Mo) was getting too heavy for his size but he loves his "crunchie" food, and eliminating dry kibbles from his diet was going to be a dilemma since I find it hard to tell him "no" (needless to say, he is so spoiled). However, my vet suggested Young Again Zero Mature to help him lose weight while still getting his "crunchies". I knew my vet's suggestion of was important to his over-all health and well-being and I tried it. Moving forward, all three cats, including his mom, Snowy and his sister, Nellie simply love eating Young Again Zero Mature. And, their transition of switching dry food brands was super easy. They, now, have been eating it for a two months and seeing Mo-Mo lose weight and still have his "crunchies" makes me a very happy Hu-MOM and a loyal customer.

Veronica Jackson, 12/5/2023

I just want to say thank you. My cat is newly diabetic and for two weeks we fought to find anything he would eat that fell into the vets approved category. We could not get him to eat a single wet food. The vet finally directed us to your mature zero. He loves it. His blood sugar is down 300 points. He is playing with toys and prancing around the house like he owns it. Thank you so much for the work you're doing! My Zeus hasn't been this energetic or happy in months. Again, thank you. You saved him.

Long Review :-) I have waited a full 30 days since receiving my first bag to share my experiences. All 7 of my cats from 4 to 13 just was not doing good and one was in terrible shape no matter what I fed and knew he had diabetes and dreading the shots to come then the others had either thick dandruff & greasy coats or both . They were on a top premium dry food XXXXXX that always smelled rotten and XXXXX can food at night and still they looked horrible so I went on a limb and I ordered Zero Mature . The first 2 weeks where rough on everyone .Squeak with the diabetes looked like his days were numbered and diarrhea was gagging from of all of them as their systems cleaned and balanced and I added in drained water packed tuna 1 can twice a day between them all due to the massive weight loss but no one refused the zero mature and it smelled clean and fresh and wonderful and within days the diarrhea started to clear up then going into week 3 Squeak started forming normal poop instead of off and on diarrhea and now all the coats are looking amazing . The short haired cats are completely free of dandruff and look like mini panthers and the long haired ones ...wow ...the greasy coats are 80% better and Squeak actually is coming into the living room for cuddles . My cats look and feel excellent just in 30 days even mama cat at 13 is blasting around the house again she has 4 - 12 year old babies :-) that she can out play them now . To say I am amazed and thankful is a understatement .The shedding has become almost null and when I brush them its not hand fulls anymore and bright eyes and talking to me and OMG and no puke every morning anymore and hairballs are once in a while .I will work them off the Tuna next month but for now with the dramatic weight loss I thought they needed a little more and most were very overweight it's been a learning curve .I'll end up saving money once I discontinue the Tuna next month so it seems high at first but when you work out the budget its still expensive but the benefits are 100% worth it.I'll update this wonderful journey at Christmas .Take a leap and put your animals on Young Again . THANK YOU !!!!!!!!!! For an amazing and true carnivore diet for my cats.

This food is keeping my cat in diabetic remission. She was diagnosed June 1, off insulin since June 15 and this food has been a lifesaver. She is no longer obese, my other cat is also interested in this food. So for right now, everything has been really good. Both cats tolerating and this is not affecting the blood glucose in any bad way. Her blood sugars have been consistently in the 90s. Very grateful for the cat diabetes support Facebook page highly recommending this food.
