Mitzi does this too occasionally. She gets really bad hairballs that make her miserable. I had her on Science Diet Hairball formula but it really wasn't helping. I'm convinced she has a sensitive stomach so I'm trying that Pet Promise food that Jen is feeding Bravehart - no animal byproducts and Mitzi loves it AND no more throwing up so far this week.

I've also discovered that the Temptations hairball treats are the perfect solution to her hairballs. She hates Petromalt, but loves the Temptation treats and they work to help her pass the hairballs out the *ahem* other end
