Thanks for the warning about the springs kr. So far so good. I usually keep an eye on them when they are playing. Mittens doesn't chew them. Mylee hasn't paid any attention to them since the first time (when I snapped the pic) and the other kitties don't get a chance to play with them. They seem to like the little mices.
Tundra - I am entirely selfish. I don't want to share the kitties with anyone. That's why I still have most of them.
