Both Emi and Eri play fetch. We've never had cats who fetch. But they both drop a toy at our feet and wait for us to throw it. They go after it, then bring it back and drop it at our feet. I've seen YouTube vids of other fetching cats, but never thought I'd have two who did.
The trick to training a cat to use a scratching post is to take them to it and extend their claws on the post. They get stuck on it and soon they're scratching away. I read that in a how to train your cat to use a scratching post article. When they were kittens, we did this daily, until they got it.
I've had one cat that fetched.
He was a rescue, literally from deaths door as a kitten just after he was born. He died quite young as a result, his health was always fragile, only Six when he left us.
He was the cat that didn't exist, no one ever saw him except us. Whenever someone came over, or came by to feed him, if we were away, he would disappear.
One time, we had a friend staying over on the couch. She had never seen him. She had never even heard him.
She was convinced we had made him up, as were quite a few other people.
She woke up with Izzy crouched on her chest, nose to nose, just purring away in the dark.
Scared the crap out of her.
Cats.
Gotta love 'em.
Good old Izzy.
