Great food. My picky girl loves this and has issues eating most other foods.

At about 6 months of age and after many vet visits, my cat Lil Bob was diagnosed with eosinophilic granuloma complex (EGC) and put on prednisolone for about 8 months. His original symptom was diarrhea that no vet could seem to control. His 5 siblings had same issue. Finally an internal specialist said to change the food which helped his siblings but then really caused his EGC to flare up. After trying every OTC limited ingredient food he finally had to go on hydrolyzed RX food. I was not pleased with the inferior ingredients in the RX foods available but they worked for his allergies. He is allergic to chicken and after much trial and error I discovered I believe he is also allergic to peas. Nearly all LID and grain free foods have peas in them and almost 90% of cat food has chicken in it somewhere. In trying to find a food for him I discovered his brother is allergic to lamb and duck. In my hours and hours of online research I somehow stumbled upon Young Again. Your ingredients were actually species appropriate and I was happy to see you had a LID food with hydrolyzed pork and no peas. Lil Bob has been on the food about 2 months now and no more breakouts except when I tried 54/22 version with chicken to confirm he had chicken allergy. Yep he has chicken allergy. He likes the food. He overate it for a while and had soft poops until he finally figured out he didn't have to eat as much. I will say that the poops on this food are much stronger smelling than on other foods which I assume is due to the high amount of protein? I have 12 cats and I am trying to get them to all eat the same food even though several of them have different issues (obesity, UTI, food allergy) . Young Again may fit the bill, only time will tell. For now it works for Lil Bob and he is off medication and the poor quality RX food so that is a win in my book.
