Yeah, Dagger (the black and white one) is the only one that has any interest in it. Saber is too old - she's like 70 years old in "human years".Plus she's just never had an interest. She's killed about a dozen cats in her life though. lol
Anyway, Dagger will play with that thing for a half hour or more...We've eaten an entire dinner, and he's still hanging on it shaking it...
