I just noticed some vomit on the floor. My cat seems fine, so i dont think anything is wrong with her. Its very rare that she will be sick. She is four, and has only been sick about 3 times altogether. One time it just came out as saliva. What im wondering is, when they vomit does it mean something is wrong? Or could it just be from eating too fast or food too rich etc? Like i said, she hardly ever vomits and is a very healthy cat. Im probably worrying over nothing, but thought id ask. Thanks.
