Dog ate chocolate?

Pregnant cat is vomiting.

Species: Cat
Breed: Unknown
Age: 2-5 years
My cat got out and didn't come home for about a month. When she got out she was in heat and she came home pregnant. We don't know when she got pregnant but we figure shes close to her due date because we can see the kittens moving. The thing that's worrying me is that she is throwing up a yellow foamy substance with a clear liquid under neath. What could be wrong with her?

I'm sorry to hear that Fire Paw is possibly having problems. (Cool name - I have never met a pet named Fire Paw).

There are a number of things that can cause a cat to vomit. My first question is whether she is still eating and acting lively? If so, I'm not too concerned about some vomiting.

However, if she is not feeling well then there are a number of possibilities. One, is an infection of some sort. It could be related to the pregnancy if there is either a mammary gland infection or an infection in the uterus (i.e. if there is a dead fetus).

It's also possible that there is something going on that is unrelated to the pregnancy. Is there any chance that she got into something toxic to her kidneys? Certain house plants can be toxic and quite serious.

Another possibility is a change in food, or eating an unusual food, or eating a foreign object.

Intestinal parasites are possible as well.

If she is bright and alert and still eating then I wouldn't be too concerned. But, if she is not feeling well then a vet visit is definitely the best idea.

I hope she is ok!

Dr. Marie.
