Constantine is a mouser. She will pretty much only eat a rat if she thinks its the last thing she'll ever eat, and then I have to put it in her hide and turn the lights off so she can eat it in secret. Mice on the other hand... you'd think I were feeding a pit viper by how much she loves those things. I got tired of throwing away money by (not) feeding rats, so I just gave in with the mice. Lilu on the other hand attacks anything in her cage so she's not much of an issue.
