Pros: Easy to chase, interactive, good way to exercise, sturdy
Cons: Chewable, possibility of tearing
This is the most simple of ideas but wow, it really gets our two cats going wild. Even our senior cat, at nearly 16 years old, will chase this around. It has a kind of snakey way of moving which gets their prey drive going. I haven't seen him enjoy a toy much at all in ages so this is a big deal! He will wrestle, grab, chew and jump at it like he was half his age. Best toy yet. Very sturdy too.
Remember this is an interactive toy - one shouldn't just let the cat drag it around on it's own. I'd periodically look at the ribbon to be sure it hasn't gotten torn up. I do this with all wand type toys anyway, nothing lasts forever, so I'm not overly concerned about choking, but one never knows.
