I have a 11 year old Bengal cat, about 1-1/2 years ago, she started go #2 on the carpet every once in a while. At first I figured she just wanted the little box cleaned more frequently. After a while, I noticed she was vomiting up her food, which was not all that frequent. We took a trip to the vet, we tried changing her food, which she had been on all her life and adding more litter boxes along with trying multiple types of litter. Nothing changed. The Vet also did a Thyroid check and blood work, which came back normal. I searched online and read up on Irritable Bowel Disease and it matched with what she was doing. When she used her litter box, her stool were normal, but outside the litter box, they were more loose and every once in a while I noticed blood in her stool. I decided to try treating her for IBD, first we changed foods again and then we did prednisone along with B-12 shots. The problem went away for about 2 weeks. After treating this way for over a month, I decided to be a little more aggressive and tried Depo shots, which didn't make a difference what so ever. I ended up having to keep her in a large utility room over night (that's when she had her accidents) a couple of months go by and nothing is getting better. I decided to try a different Vet just to get a second opinion. This Vet also did a Thyroid check and blood work (again came back normal) and also noticed a broken upper Canine tooth which had been that way for around 4 years. He thought that this might be a contributing factor, so he did a tooth extraction and then followed up with antibiotics, nothing changed. I started searching online again and came across Feline Tf, I went back to my original Vet and decided to do a PCR test for Feline Tf, which of course, came back negative. I have spent a lot of money in the last two years trying to get this problem figured out and I am trying to avoid having to euthanize her. Has anyone else had to deal with this type of problem? Any help is very much appreciated, thanks.
