occasional bloody diarrhea
My cat (1 1/2 yrs old) had diarrhea on and off for about a month, occasionally with bright red blood in it. In this time she switched foods a few times, and was subject to some stress(long car rides, a new environment with other pets). I took her to several vets, and had a stool sample analyzed, which came out negative. She is currently on Hill's c/d-s diet. For the past few weeks, she has had normal stools, with one isolated incident of bloody diarrhea. Throughout this whole time, she has been energetic and has maintained a very healthy appetite. Essentially my question is, is it possible for her to have had these instances of bloody diarrhea and be essentially healthy? The vets I have seen haven't been able to make a diagnosis, and I don't want to subject her to continual vet examinations and blood tests, x-rays, etc if this is not necessary.
