cat vomiting

My cat is vomiting about every 2 weeks for 2 months now. What should i do. I have been grooming him more and served him less food. But nothing seems to help.

Do you mean that your cat is only throwing up once every two weeks? Is it hairballs or food?

Don't restrict food. My first guess is that it's from shedding season, so brushing should help. It does not sound like an alarming amount of vomit though.

Grooming more often is good for hairballs but he may need something else to pass them as well. 

Here's more information about why cats vomit and what could be done about it.
