He is clearly retching and heaving be
fore he vomits, and his vomit was a small amount of brown/dark green liquid
mush. There was no blood or objects. I have already done a little research on the possible causes, but I cannot seem to pinpoint what
is actually causing my cat to vomit. I will be
taking him to the vet soon, but I would like an idea of what
is going on be
forehand. Thank you for any help!
