Delay the CATastrophe

Your mum is nice. She even looks after stray cats.

There's just one problem. She keeps dropping them off at your place, and these cats are NOT trained. 

Prevent fights from breaking out as you get these cats to coexist. It's not easy, especially when mum just keeps. Coming. Back.

Pick up cats that look like they're about to fight and keep them separated until they get used to being in the same room as the other cat. Just be warned - they have to get used to EVERY cat your mum brings to your house. There WILL be fights. It's inevitable. But try your best not to disappoint mum, yeah?
