Hi, first time posting! I live with two domestic short hair kitties, 9.5 years old, female, from same littler. They are on modified Dr.Pierson's recipe almost two years. Modified means - (1) I buy ground from Hare Today instead of grinding myself, (2) I use different kind of proteins, Chicken, Rabbit, Turkey, Pork and occasional Duck. One of my kitty start having vomit incidents since Mid-December. First I thought it was emotional (I needed to travel 2 weeks in row after Thanksgiving, left them with cat sitter lady). Then I sort of linked her vomit with Pork, so stopped feeding Pork. Over the Christmas/New Year I traveled again, kitties ate canned only when I was away. I came home, start re-introducing raw. Seemed doing OK, but she did puke 4 times in January. She's been on half raw half canned lately. PUKE HISTORY Her puke in December were 1-2 hours after raw meal, food came out. Happened 4 times. 1/7 after Rabbit raw 1/8 after Pork raw 1/16 yellow bile no food 1/17 yellow bile no food tiny hair ball 2/9 yellow bile no food 2/9 after Rabbit raw WHAT IS KNOWN Her sister is eating raw just fine, i.e. no bad batch I did not change recipe at all Met Vet, was told that she is in good shape (visual inspection only)(she had full blood panel in summer) Activity wise she is fine. No change, sometimes quite active, cold and cloudy days are sleepy. Her "output" is normal WHAT I AM CURRENTLY TRYING Made bone broth Will start primal goat milk (bought today) QUESTION Did any kitty experience something similar? If so, did she/he ever able to go back to raw? Or ended up settling down with canned or cooked food? I am wondering maybe Probiotic or digestive enzyme might help? I am really hoping to go back to raw, or possibly home cooked. Buying canned food is very difficult after making raw ... there is almost always some ingredients I think "???" ... Any comment is appreciated. Thank you very much!
