Cat vomiting causes are many and varied but in fact, cats often regurgitate undigested food which hasn’t actually reached the stomach. Real vomiting is the ejection of the stomach contents, often preceded by salivating, retching and the contraction of the abdominal muscles.
Cat vomiting causes can be related to eating or to illness.
In the case of eating related cat vomiting causes the cat may have just eaten too fast. Alternatively, a change of diet can cause vomiting as can food which has gone off or which just isn’t suitable for cats.
More seriously, the cat may have developed an allergy or intolerance to certain types of food but even more dangerous is the ingestion of some kind of poison, which incidentally includes aspirin, or some sort of foreign object like a piece of bone or part of a toy.
If a cat has worms it can also cause vomiting as can a fur ball which is a hard ball of the cats own fur which collects in the stomach due to the cat grooming itself.
There are a huge number of cat vomiting causes relating to conditions and diseases. Some of the more common are diabetes, gastritis, heat stroke, an over active thyroid, liver or kidney disease, pancreatitis, feline enteritis or some sort of infection.
If the cat’s vomit contains large quantities of undigested food then the cat has probably just eaten too fast but do watch out for repeat occurrences. A sort of coughing retch which produces either nothing much or a sausage shape is probably caused by a fur ball. On close inspection, the sausage shape may prove to be the fur ball, so you needn’t worry further. If the fur ball hasn’t appeared then try treating your cat with kitty malt or fur ball treats but if the symptoms continue, take the cat to the vet. If it is a seriously large fur ball which won’t pass one way or the other, he may treat the cat with liquid paraffin which, while unpleasant, is very effective.
If you have any reason to believe that your can has eaten something poisonous which can range from actual poison put down by neighbours for rats, some plant seeds or drugs intended for humans, then go straight to the vet. Don’t delay as the longer the poison has to invade the cat’s system, the more likely it is to be fatal.
If your cat vomits frequently or displays other symptoms such as diarrhoea, weight loss or lethargy, then go to the vet. If you can take a sample or the vomit and/or faeces, it will be helpful as the vet can get it analysed. It will also be helpful to tell the vet about any change of diet or other habits and anything else you can think of which may aid diagnosis.
If the vet can’t immediately identify the cat vomiting causes then he may want to carry out blood tests, x-rays or ultrasound. In the meantime, he may prescribe a broad spectrum antibiotic in case there is an infection.
Whatever the cat vomiting causes, don’t let it go on too long before seeing a vet; unfortunately your cat can’t tell you what’s wrong so it’s better to be safe than sorry.
