Something wrong with my cat

I'm not sure. She may be eating too much or not drinking enought water. Ask your vet.

Ok, don't panic, the grayish and watery is very NORMAL cat vomit, and nothing to worry about, this is caused by excessive grooming. The yellow and green is often associated with excess hormones in cats in heat. This may happen several times during the heat cycle. I, of course, must first recommend you have your cat spayed as soon as possible, this will prevent unwanted litters, uterine infections, as well as several forms of cancer in your cat later. Beyond that, watch for bloody vomit, bloody or mucusy stool, watery eyes, and lethargy, if your cat develops any of these symptoms, see your vet ASAP. If you need contacts for low cost spay clinics, please let me know where you live and I will be happy to recommend one.

It could mean she is pregnant

The anatomy of a cat is the most closely paralleled to the human than any animal. Cat throwing up green yellow bile which is normal coloring for stomach bile. A cat licking itself may be simply the nature of the cat in meticulously bathing themselves. An animal showing defense when an attempt is made to inspect, particularly when licking self, could be an indication of a bone trauma, which needs to be evaluated by a veterinary specialist if the cat does no improve quickly. Often, particularly in animals breaks are not realized. In inflammation from a brake always presents 1 or more of the following: pain, fever, swelling, redness. If anything about the cat seems particularly not like it should take the cat to the vet. Sometimes the Humane Society will work with you on a sliding scale if you can't afford full price.
