Those are awesome, but somehow i think my cats are too snobbish to play with them XD
And I just noticed your avatar... that tattoo on your back, my mum has what seems to be the exact same design, but much smaller and on the bottom of her back.
No cat can be a snob with enough catnip
And, your mum must totally rock, haha.
Haha, my cats can be snobs even with piles of catnip, believe me! And my mum does rock. ^.^
