I have a very busy 11 month kitten. If she is not sleeping she is prowling around begging to play or finding things to get in to. She gets bored with the automatic toys that become predictable, but still loves this after more than a week. We are using the yellow snake, which slithers on the floor but can also "fly". There is elastic in the toy attachment so in addition to what the hooman can make it do, if it momentarily catches on something the elastic makes it jump by itself. The yellow snake is coming apart a little at the tail due to all the biting from the hunteress but it is made of soft material inside. I still laugh when the cat gets a good grip on the snake, tries to run away with it in her mouth and gets furious when the rod follows her.
