Great he doesn't have Pancreatitis but what did they say the problem might be?
SEB is supposed to coat the stomach, did you try that? I think you need to wait a few hours after meds.
First time I skipped Ravan's shot & his bg went up only one cycle then right back down.
Is he still vomiting? I just thought of something didn't you put flea collars on them recently? I just read this
Are Flea Collars Safe for Cats?
No, flea collars are generally not safe for cats. They work by either emitting gas that is toxic to fleas into the area around the cat's head or by releasing chemicals into the pet's skin.Cats are extremely sensitive to chemicals, so they can be particularly sensitive to flea collars.
What doesn't bother one animal might make another one sick! (just trying to get some ideas of what could be making bella sick?)
