Both Max and Speckles are indoor and have never seen a "live" one.

Speckles seems to be more outdoor friendly because she loves the balcony. She'd probably go after a live mousie but she'd never catch it because of her *cough cough* wide girth and the fact that she came to me declawed.

Max on the other hand would probably sniff it then run and hide. He's such a wimp; even a gust of wind sends him under the couch.
