Feeding Instructions

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. Please do not use distilled water with our food. We recommend spring water with a neutral pH.

My cat who has eaten the Mature version for about six months just got back "PERFECT" bloodwork. She had been very thin and her kidney values were rising this time last year and the vet had put her on a prescription kidney diet, which caused her to lose weight and gave her itchy skin. She has no itchy skin now, has gained a full pound, and has perfect bloodwork. She is almost 14 so I was thinking of switching her to the LID Zero since she is no longer thin, since it appears that is best for kidneys. In all events, thank you SO MUCH for such wonderful cat food!!

This cat food saved my cat's life, I'm quite certain. He was diagnosed with early stage CKD and was already wasting and sitting like a loaf (which is an uncomfortable stance cats with kidney disease take when they are suffering). I had tried to get him on all wet food but no matter what food or method tried to get him on all wet, no matter how slowly I transitioned, the cat would starve himself... Nothing was working. I was prescribed medicated wet cat food for cats with kidney issues but I'd already read that the high protein is less of a culprit than high phosphorous in foods and didn't want to deprive an animal that lives in the wild of protein if it wasn't absolutely necessary, I came to find Young Again recommended on a well respected forum for caregivers of cats with CKD so I ordered a sample and my cat LOVED this food so I placed the order. This was three years ago and I can't believe how my cat's health improved in that time. He's now 14 years old going on age three! he's a kitten again actually, what a perfect name for the product!!! Within a year, his BUN and Creatinine were perfect, no sign of CKD in the labs or in his behavior. Everyone comments on his beautiful soft coat...He is beyond personable and friendly whereas he'd been a little withdrawn when he was sick (as would anyone). He is aos playful and happy! Another amazing benefit is his improved gut health, He has thrown up more than most cats and not just fut balls since I adopted him and I'd tried every probiotic and supplement and every expensive grain free wet and dry food (he was half and half but always preferred dry) but nothing worked until Young Again made his gut so healthy...he's a purrfect weight as well! Before he was skinny from the kidney issues, he'd been on the obese side, and now he is just perfect, the vet says. My vet has recommended this food to others after I explained what caused the health improvement (the perfect kidney labs blew him away!) This company is the best. Even during the worst of the pandemic, they alwasy delivered this essential food quickly. I am so grateful!!! It might seem a tad expensive but the vet bills were piling up and actually I already spent a bundle on food (including the food he constantly rejected, now I never have to switch) so I feel this food is a bargain and I'm saving tons! Anyway, I would spend ten times the price to see my cat thrive like this after so many months of watching him deteriorate. Thanks again. This is a real review, not written internally...who would write something so rambling except a crazy cat loving lady like me. Thanks so much!
