http://www.ng2000.com/fw.php?tp=catsBy JEFF KAHLER I have heard it said by several people over the years, some veterinarians, that it is "normal" for cats to vomit on occasion. I am not sure I would concur. I do not consider vomiting to be "normal," but I do try to decide whether the vomiting is a problem that needs to be addressed.

I recently had a cat pass away after being with me for nearly 20 years. It was a rare week where my dear cat didn't throw up at least once. My cat had a thick coat of fur and she was fastidiously clean, so she would hack up fur balls. I tried giving her medicine for it, but it didn't really help. Brushing her helped, but not a lot. I discussed the situation with my vet a few times over the years and he said it was just normal behavior. Considering that my cat lived nearly 20 years before kidney failure got her, I think my vet was right.

That depends on what it is they are throwing up: hairballs indicate you aren't grooming them well enough; food usually indicates nothing important unless it occurs after nearly every meal, in which case it is time for a trip to the vet; clear liquid may or may not be serious.

I've had 7 cats in the last 25 years (four at once at one point) and I would definitely say it's normal for cats to vomit on occasion. Sometimes it's a fur ball, sometimes they've nibbled on a plant and it makes them throw up. Sometimes there's no obvious reason. No need to panic unless it's frequent. If one of my cats began vomiting more than once a week, and I couldn't attribute it to a fur ball or plant eating, I would probably become concerned.

I have one who vomits quite a lot..She has loose hair, and sheds a lot, and throws up her hairballs..So, it can be reqasonably "normal". For sure, it's better than paying $800 for an operation to remove a massive hairball from their stomach..Which we had to do for another of our cats last year..

For cats, they don't 'vomit' what they are doing is removing an indigestible amount of hair or fur that they swallow while they lick themselves. If it can't go through the digestive system they will 'vomit' to get rid of it. If you are concerned about your cat try giving her/him a little butter, margarine, or oil mixed with some canned food. This should help to reduce the frequency of 'purging'.

It depends how often. Once ia week one of my 3 cats will upchuck, and it's always a hairball (or hairslug since that's what it looks like). So, on average, each cat upchucks once every three weeks. I often don't know which cat did it.
OTOH, I once had a cat that vomited every day or other day. He had some sort of intestinal problem that finally killed him (after costing me a few thousand dollars to find out what was wrong and treat him).

I let them into my fenced-in backyard when I'm home. As soon as they go out, they find a few nice blades of grass and start chewing away.That often causes them to upchuck. I think that's why they eat the grass.
