mine like the Cat Dancer, Da Bird & laser toys... also Chip likes catnip stuffed toys. Java likes things with fur on them. Cable likes 'skittery' things, like ice cubes, plastic rings, etc. Pixel prefers soft toys - tissue balls, soft foam balls, & the like. Firefox hasn't shown a preference, yet. Mouse liked pingpong balls. but they all prefer toys that are interactive... meaning i have to play, too!
