there's a certain kind of toy mouse my cats like.
they have others of similar size, shape, covering, noise (a rattle sound) but they ignore them.
Barney will bring it to me to throw for him over and over when he's in the mood. Drop it on my foot or under my chair, then stand on hind legs with paws on my thigh and do the "i'm sending you a telepathic message" thing that cats do. if that doesn't work, the claws go into my thigh. THROW MY MOUSE!
after a bit the mouse disappears. totally! i've searched under furniture with a flashlight, used a stick under the fridge, cleaned the house (after my fashion). gone.
these mice are sold loose from a bowl in the pet supply store. lest they suddenly stop making them or stocking them, as so often happens, i bought a bunch of them to dole out on days when the cats are bored to crabbyness. they are popular for awhile, then GONE. VANISHED from the earth.
recently john gave them a new orange one. hank ate the tail right away. by the next morning the orange mouse was still in evidence, and a red mouse had appeared in the food dish.
by that evening a green mouse had turned up on the rug behind the rocker.
it seems cats have access to some parallel universe. perhaps our missing socks will begin to reappear now that the portal is open.
