Ken,

Sorry to sound gross, but are you seeing hair clumps when you clean up
the vomit? It would look like a clump/lump, usually cigar shaped.
Seems unusual to me that she would get hairballs if you brush her
daily. Doing this daily doesn't sound good--you might call your vet's
office and ask. If she were doing this weekly, I wouldn't worry, but
daily is not normal IMO.

Your comment about more hairballs since starting Wellness is curious.
Since my cats have been on canned Wellness (and some Evo), we've had
fewer hairballs.

You can try and add a teaspoon of plain canned pumpkin to her food and
mix that in. (Some cats like pumpkin and will eat it as a treat.) If
she's currently experiencing hairballs, you can give her Petromalt or
other hairball remedy for a few days (don't give near her feeding
time. It will reduce absorption of nutrients.)
