What have you all found to be good toys for ASFs.

Mine don't destroy or play with paper or toilet paper tubes

Am looking for more ways to enrich my breeders lives.

I picked up some cat balls that they love to pick up and carry around.

They also have a wheel in their cage, but they all tend to sit/use it at the same time so it's gotten bent (4th wheel >_>) an keeps squeaking. Could maybe a wheel made for a larger (guinea pig, rabbit) last longer since it's made for more weight?
