Hey there, thanks for all the advise. She is our first cat. Although we have 4 dogs and a sugar glider. All the dogs are on a grain free food. They'd be on a raw diet if we could afford it for all of them!

The lady we got her from gave us her remaining food supply. She'd been with us for about a week and a half before she started having hairballs. Where she'd never had any with the previous owner. Could some of this be that she's catching a lot of field mice? And eating some of them? It was about the time that she stopped bringing us her trophies, and we started noticing mouse parts around the house, that she started having hairball issues.
