They'll have a ball (substitute)! They go wild over that little red dot, chase it everywhere. You can be a real couch potato with that thing. Not like with a dog where you have to reach down to pick up the yucky wet ball from the floor where the dog dropped it!! LOL
I'm very happy to report that all three of the kittens can see color very well. They chased that thing until they were panting and momcat hissed at me ;) I even got a toad to chase it - guess he thought it was a firefly.
These are all feral cats BTW ... mom had her litter in my garage about a month ago, and none of the kittens are the same color (mom's apparently a wild sort). The little black one will come right up to you, but the other kittens arch their backs and spit just like mom does when a big mean human gets anywhere near them.
I don't think I've had a better Saturday night in a long time.
