A roomy box is best - one that is made from very sturdy cardboard. Our cats love to hide, jump in and out, and play King of the box.

Pros: great

Cons: none

These are the cheapest, most fun toys you can give a cat. It will entertain them for hours on end. My cats love them so much.

Pros: So fun

Cons: None

The cats have such a gteat time with boxes and bags. Who needs to buy toys when you can pull them out of the pantry

Pros: The best toy ever

Cons: None - its free

My gerbils love a good box to chew up, and plain old cardboard is safe and free of dyes.

Pros: cheap, recycling rather than tossing

Cons: none

Can't get better than this. Doesn't cost anything, loads of fun and tossable!

Pros: No cost, no mess

Cons: None
