Pusscat 3, mice 0

 ...of course, we only have her word for it, based on what she brings home.
But she was darned if she was going to let Robert take mouse no. 3 off her when she triumphantly announced her prize to the house today.

It went straight under the sofa and into the  kitty pie for safekeeping, where she could play with it undisturbed.
