Zero Mature Health


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.

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:

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.

Wow. This food is a diabetic cat moms dream come true. We have four cats (ages 4yo-11yo), and one of them was diagnosed with diabetes about a year ago. We initially tried “keto kibble” but its insanely expensive and the use of beet fiber makes the kibble so hard one of my cats couldn’t chew it (and would just barf the pieces up whole). We tried switching to a good (but not necessarily diabetes friendly kibble) hoping that if we got our diabetic cat to fill up on carbohydrate free canned food he would more or less leave the other cats kibble alone because we have always free fed kibble (nope, that lead to him almost dying of ketoacidosis because we could not keep his blood sugar under control). I heard about youngagain in a group on facebook, and thought I would give it a try. I am so glad I did! All four of my cats took to it immediately. Within 24 hours my diabetic cats blood sugar was at 286 with no insulin (usually he would be well above 600 with no insulin which is scary!!). We had been giving him 3-5 units of insulin twice a day and were barely keeping it under control. He needs so much less insulin on this food. Its incredible how much a simple dietary change can make. When you consider the serving size compared to other food, one pound of this food lasts us twice as long as our previous kibble. Combined with the fact we need less insulin, this food is definitely saving us money (and saving our cats health!!!). Seriously, this kitty kibble is as close to perfect as you will find. Do yourself (and your cats) a favor and order this stuff right meow.

My old cat is a hot mess of diseases (diabetes, kidney failure, liver disease, heart murmer, chronic nasal infection and utis... ). She was staying in the hospital for 4 days at least once a month in some crisis. As a diabetes got to the point of needing treatment, she was very anorexic and we just frankly expected she would die within the next couple months if not weeks. She refuses all of the under 5% carb wet foods - so that recommended diabetes diet is out. This and another brand saved her. At first when I got sample she preferred the other brand. But as she got acclimated to this one this became THE ONE AND ONLY. It is all she'll eat. And she actually comes running when I put fresh food in (even though i free feed!). She's put on the perfect amount of weight, and has a great appetite now even when she's all sniffly and can't smell the food. Her kidney numbers at the vet are much better, and her diabetes numbers are between 100 and 180 at all times. I feel very comfortable with the routine, and it's no longer a 'wait to die' or constant struggle just to keep her alive- she's just living and living well. And so are we!
