My Mrs has been making Pompkins so that she can play with our cat, Munch. I reckon people will like them and she's said if someone buys one that she'll consider making them and selling them along with other a few other styles.
They have a woolen length attached so that you can tickle it around the floor and dangle it for your cat.
I'd recommend being in the room whilst your cats playing with it, and keeping it away from your dog (Baz, our dog, acts like they're raw meat for some reason and will run off with them).
As far as we're aware the glue used is safe for your cat, but if your cat starts chewing the mouth bits please take it off of it and remove them, just to be safe - against popular belief I don't want to kill animals.
