Vomiting in cats
If your cat is vomiting in an unusual fashion and looks or acts ill please take him/her to the vet ASAP.
One of my 2 cats vomits regularly. When I say regularly I mean on average 2-3 times a week. Ziglet usually vomits his food and when I have asked the vet about this in the past, he has suggested that it's because he eats too fast. But aside from the vomiting, his behavior is normal. He does not do anything unsual for his character. Had he vomited continuously or started exhibiting behaviour that is out of character (like hiding in places he normally doesn't frequent, or lying down in a way that is unusual for him), I would have called my vet immediately or brought him to an emergency vet.
My other cat Zak has had some extremely serious problems in the past that involved vomiting. During 3 episodes in particular he vomited about 5 times in a row - so that there was no food left to vomit. He just vomited stomach acids after that. He looked and acted unusual and exhibited this primarily by lying in an area that he never lies in and staying way too still for his character. He continued to purr the whole time I was checking him out because I was already suspicious. After an hour or two there was no change and he still kept vomiting so i brought him to our vet. The vet said he was dehydrated and took x-rays which showed that he has a bowel obstruction. He needed surgery to remove a bird's neck from intestine. Had we not done the surgery the vet said he would have surely died. This EXACT phenomenon happed 3 times but with a bird's head and part of a mouse obstructing his bowel the other 2 times. Zak is now an indoor cat and has been for about 7 years. I did not have pet insurance at the time, but you can bet that I do now.
