Thanks for the welcome messages. I'm really hoping for some help with this cat. When we first went to feed her she didn't seem to know what cat food was at all and she won't drink water from a bowl. She's happy to drink it if the tap is running or out of puddles though.
This seems to indicate she hasn't actually been fed properly, if at all, at her previous house. I could be wrong though, maybe they fed her pellets, but she was a really avid hunter.
