My cat has IBD and is only on S Boul. no other meds. (she suffers from runny bum but never usually vomits). Runny bum wouldn't clear up just lately (although not dreadful) (she is on Catz Finefoods pork , kangaroo etc mixed with poached mince pork & someone suggested I try a little plain poached white fish & feed that only. I fed this & nothing else for 2 days & no poop, then on the 3rd day I added back in a little poached pork mince &........ explosion! So I have gone back to the plain poached white fish & no poops since. Am I doing the right thing and how long can I feed this for? Today 50% of the time she has started regurgitating the poached fish straight back up (even if she only eats a bit at a time), but after regurgitating, if I offer a bit more say.... 1/2 later she keeps it down.......strange! Am I doing the right thing with the fish?
