When I was a little girl, my older brother had white mice for a science fair experiment. "Speedy" was my favorite, he DID run the mazes the fastest, too. My brother is 8 years older than me, so I was maybe 7 or 8, but if I held really still and promised to be very careful, he would let me hold Speedy, I still clearly remember the feel of those teeny teeny pink feet in the palm of my hand! We were careful to keep the mice separate from your German Shepherd, though. They eventually died of old age, such short lives they lead, them micers, but it was great fun having them around!

So the cats think of the mice as entertainment?
