i have a few that will reach thru the cage bars and snatch, but i have one girl that i swear doesn't see well. she gets my thumb all the time. sigh, it is beginning to toughen up. i like the snatching though, as well as being safer for my fingers, it is hilarious to watch how far they will reach out. then i have a few that will politely take them with their mouths in a genteel manner.
