Fabcats will go crazy for these toys! They can all be swapped with any Fabcat teaser. Each teaser has a hook to open and close, and each toy has a loop to connect.
My cat adores these stuffed sharks I found at a local pet store. When I had to replace one of the sharks, King Duke's was the only place that seemed to have them, so I ordered four. King Duke's shipped right away, and their service was excellent. Highly recommended.
