IBD

I believe there is a food formulated strictly for IBD. It's not Prescription either but comes from the vet - not cheap.
Another cat board I belong to lots of people feed their IBD cats that food (can't think of the name) and it helps

I did a google search and most of the sites suggest a raw diet

Our cat was never specifically diagnosed with IBD, but she had terrible intestinal symptoms... as you say, awful poops. And she was a very calm, quiet lap cat.
 
First, the vet suggested Eukanuba low residue kibble. That did not work. Then Eukanuba prescription canned (can't remember the name). That worked to clear up the diarrhea, but only if I was very strict about the amount she ate, never gave her treats, and fed her on a strict schedule.  I began doing some internet research on cat nutrition...
 
Long story short -- switching to a premium food (Wellness canned) cleared up her symptoms in no time, and gave her a ton more energy. She's not a calm, quiet lap cat. She's a curious, bouncy hellion! Apparently, she just felt bad before. 
 
Switching to a raw diet has improved her even more! We really like the Nature's Variety Prairie pre-made medallions, and for a small cat it doesn't cost any more than the average canned premium cat food.
 
Good luck with your kitty. IBD is miserable.

Cindy- I know this is off topic,but your corgi is too die for!I love the reds, but am partial to the tris.

Thanks for all the input on IBD for poor stinky kitty. She hasnt been wild about canned but I will give a try, I'll do anything for a better smell. lol
Can they ship the raw food??
 
Tiffy,Thanks so much, we just fell head over heels for darci. I love your tri baby, so sweet. We are actually thinking of getting another corgi and would like to get a tri. We were thinking of getting a boy ( no breeding ) beacuse darci is pretty much ruler, we were worried about adding another female.
Plan on talking with a breeder lot's more before we decide.
