My trained one of her house cats to fetch. Never would have believed it was possible but she did it
One of the Siamese female cats Mom had would retrieve her toy rabbit fur covered mouse over and over for you. She’d hop up in your lap and drop it then wait for you to throw it again. Till you got tired of it. 🤪
GF and I had a cat, and taught it to fetch. Same as you, he would do it until you were worn out.
She also trained him to lay down and roll over on command. It was funny stuff to watch. Also put a small rubber snake about 5' up on a cabinet with the tail hanging off. Cat would jump up and knock it off with a paw.
