Took Bobo to the vet around 7 months ago, with symptoms of throwing up blood and bloody diarrhea , when he has these spells which are usually every 6 weeks or so, he acts like he wants to eat ,but turns it down, then comes the throwing up of watery pinkish to red blood and bloody diarrhea . The vet prescribed hills d/d duck and green pea diet along with a probiotic . He got better and began eating with the others ( I have 3 other inside kitties that I feed pro plan ) . But like I said he seems to have a cycle , and that came back .The vet was hesitant to diagnose him with IBD but thought maybe his opening to his stomach was too small and when he ate it caused irritation , which caused him to regurgitate blood and then swallow it causing the problems . 2 months ago my outside cat got a respiratory inf that the inside kitty's got, $650 later everyone was fine except Bobo , I didn't think he was gonna make it , luckley I took him to a new vet that gave him a 14 day Atb shot and he made it . Butt now 2 months later we are back to the same old problems , sorry this post is so long I just wanted to give as much information as I could . The last time after he got over his resp that he went through , it actually took about a week for him to eat ! Just want to know if anyone has anyone else has had this happen or any advise? Different diet ?
