My bunnies like toys too. Some of their favorite toys are not purchased from a store though....
Chocolate loves to toss around a small empty margarine tub and/or it's lid, an empty roll of TP is great fun too. Daisy loves the sound of tearing up old phone books and newspapers. If I'm not careful, he'll rip apart bags of litter and then I have a real mess to clean up. Plastic measuring spoons are fun as well as some infant baby rattles. They all love the cat toy that's a spoked barrel with a small bell inside...plus I can find them when they are playing with it!

Michigan Rabbit Rescue has these great plastic cat castles for their buns...they are large, 4 ft w x 4 ft d x 3 ft h and have different levels and windows to jump through and sit in. Unfortunately the company stopped making them so I'm looking for a replacement. If I find something I'll post it.

It really is fun to watch them play!
