I ordered a catalog of cat toys and there is a toy I wanna get for T & J sooo bad....... there is a variety of ones to choose from... like a frog or duck or lizard.... any way each one has an appendage that you pull ( like the lizard his tongue and the duck his tail etc. etc.) and while the tongue or whatever pulls back in the toy will vibrate and move around........... I BET MY BABIES WOULD JUST LOVE IT!!!!
