Cat with transition cells in bladder - Answered by Dr. Lee

[Sun and Sand]

Our 12 year old cat suddenly started hiding under the couch about a week ago. He wouldn't pee or drink but would eat his food. He would hiss at us when we took him from under the couch. He is normally a very affectionate cat. So, we took him to the vet where they have finally diagnosed him as having a thickened bladder wall and also transition cells in his bladder. Although they can't say if they are cancerous or not. They have him new meds and an IV and he is doing much better.

We are worried though, what are transition cells? What will happen to him? What should we be doing?

Any help on this would be most appreciated as we are very confused. Thank you.
