Tucker, Mystic and Abner all are allowed outside when my husband comes home from work (they were all outside drop off cats when I took them in) and they also love to play with their mice. If I happen to be outside with them I will make every attempt to do a mouse rescue, but sometimes that does not always happen as they love to run under the deck with the poor critter. They all turn into "mad cats". They throw them up in the air, bat them around the ground, run with them in their mouths, etc.
