5 month old kitten, chronic diarrhea, been to the vet a lot
I adopted a kitten from a shelter. Since the day i got him he has had diarrhea. List of things we've tried.
new diet (u/d and i/d, bland diet and low allergen diet)
tests for fip, fiv, toxoplasmosis and feline leukemia (all negative)
zithromax, panacur, metronidazole, blood work, x-rays
recently started him on his first shot of vitamin b12 and did a tli test from pancreatic enzymes (which i should get results of in a week)
examined (float test) and cultured for saminella and something else (i can't remember) and still nothing
Everything is negative, indicating he's healthy. He makes a farting noise sometimes when he goes to the bathroom (esp when it's worse). sometimes it's fully diarrhea, sometimes it's just really loose, but never solid. He drinks a ton (but the bloodwork said he was fine, not indicating diabetes) probably due to the diarrhea.
besides this, he's healthy, gaining weight and playful. He never misses the litterbox and he's great. Any ideas of what to do next? Any other opinions?
