YA ZERO Mature is formulated to meet the nutritional levels established by the AAFCO Cat Food Nutrient Profiles for maintenance.
ZERO Mature Health Premium High Protein Cat Food
Like lions and tigers, domesticated cats are obligate carnivores and by definition have no nutritional requirement for starch/carbohydrates or plant proteins in their diet. When a feline doesn’t eat her natural diet – meat and fat, she can become overweight and at risk for diabetes. Young Again Zero Mature High Protein Cat Food supports your pre-diabetic or diabetic cat by giving her a carnivore-based alternative to traditional cat foods. No starch or plant proteins. As your cat matures, her body also requires less calcium, phosphorous, magnesium and other nutrients. Excess levels of these nutrients can actually create health problems in CRD and aging felines.
Recommended for felines that cannot tolerate excess starch.
Young Again Zero Mature Health Premium High Protein Cat Food:
Your cat is considered mature as soon as they are done growing bone. For most cats that will be at about 2 years of age. However, for 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.

There are two ways to feed Young Again Cat Foods:
At YA, we highly recommend Free-Choice feeding. Please follow the instructions carefully. For additional feeding suggestions and assistance, please read Transitioning your cat.
If you must restrict feed your cat, please use these guidelines:
Average consumption for 24 hours:
8 lb. cat – Level ¼ cup
10 lb. cat – Rounded ¼ cup
12 lb. cat – Level 1/3 cup
15 lb. cat – Rounded 1/3 cup
20-25 lb. cat – Level ½ cup
For Maine Coons and other giant breeds add ¼ cup to each of above measures for 12 pounds and up.
PLEASE NOTE: Because Young Again is a nutrient-dense food, your cat will eat MUCH LESS than other cat foods. It does not mean your cat does not like our food.
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.
