Hey Bastetsmum, last year I was on a cat show and the judge there wanted to show people how different the character of kittens could be: There was a cute black British Short hair: he could hang it over his arm like a towel -the kitten relaxed completely. Then there was a 12 week old Aby...... You can imagine -he had a feather toy and little Aby went crazy.
I think for them a natural tree with some feather ornaments would be the purrfect Christmas gift.
