My brother had a cat that would fetch. It needed to be 'aroused' by teasing it for a while, chasing a stick held in the hand around the yard first. It would then fetch a stick thrown a few feet away. I witnessed it drag a 10 foot long newly cut tree branch thru a cat door (at the back of the cleaning cupboard and thru that door as well) into the hall then mew for somebody to keep playing.

This is the cat I found head down, eyes closed, tongue working like a toy, up to the ears in a cup of egg yolks left over after making a pavlova. Picked it off the bench, put it on the floor, it didn't notice it had been moved for a few minutes...

This cat would also eat dead matchsticks...

I'm not making this up you know, I'm not that clever...
