Mine aren't big on toys. Rusty has a jingle ball that he throws around, but he usually only throws it when he wants something! We joke that he could be a basketball player because he stands up on his hind legs and throws the ball really high!
He also throws it into his water dish or his litter box. I have a thing that hangs in Sonora's pen and it has wood chews on it. She likes to chew the wood and throw it around. Their favorite toys are things that aren't toys.
They loves boxes, so we give them boxes to play in and chew up. They like jumping on top of the boxes too. Sonora likes to chew and dig in the carpet. They like to play in towels and blankets. They will dig and push the towel around. They like plastic bags (of course this is not a good toy) but if there is a plastic bag in the room, they will dig in it (under my close supervision, but i don't suggest that as a toy). Have you tried paper bags? He might like to play in and chew up a paper bag. They also like to play in the cat carrier. I put a towel in it and they love to go in and throw the towel around and hang out in there.
My bunnies like to play games. They play chase with the cats. Rusty is very curious and he likes to climb on things. He jumps on the couch, and if I'm sitting or laying down he climbs all over me. They also like to make a game out of getting hay out of the hay bag. Its the same hay as whats in their bowl
but they love reaching up into the hay bin and pulling the hay out of its bag, strand by strand. They both get a big thrill out of that. They also like coming into the kitchen to get treats out of the fridge. I usually give them a baby carrot if they come into the kitchen when I'm in there. So my bunnies are mainly into games and activities. They have a lot of toys but they really don't play with them that much. There is a cool toy that looks like a bunny. Its plastic and it has a bell. They try to push it over and it bounces back up. They like to push that thing around. You can put hay or treats inside it too.
The Busy Bunny is a cool site!
