Our cat, Baby, had either inflammatory bowel disease (the human term for it which is why your vet is calling it inflammed bowel) or alimentary lymphosarcoma. Both illnesses present with the same symptoms, so be sure to ask your vet about this , he may want to do bloodwork. Unfortunately, the sarcoma can only be confirmed with an intestinal biopsy, so if Skinny is older, then your vet will not perform this procedure (as in our case). Baby did well on Purina DM for a while and then preferred beef flavored baby food towards the end which we supplemented with K/D (?) when we thought he wasn't getting enough nutrients. Also, do not use any furball preventative and no more treats as these irritate the bowel. All helped somewhat with his stool (which never went back to tootsie roll consistency by the way, but did improve), along with daily pills of prednisone along with an anti-nausea pill. Also, watch his water intake - using room temp water as opposed to cool or cold water and if you have a water softener and use salt pellets, consider changing to potassium. Hang in there because you will constantly be adjusting his diet - you have to be consistent in what you are feeding him but at the same time, once you realize that diet is no longer working, be prepared to change it again. You will constantly reassessing his diet and condition for the rest of his life. I hope in Skinny's case that it is inflammed bowel and not alimentary lymphosarcoma and that he lives a long healthy life - Inflammed bowel is manageable but don't ever expect his bowels to go back 100% to the tootsie roll form you are seeking. Best of luck to you and health to Skinny!
