These are good, and at $3 or 4, they can just be replaced when they're too gross for words or to shredded for words

Pros: pads wire bottom cage, fun to chew

Cons: gets kinda gross and hard to clean

my bunny loves this and it keeps her entertained and happy...

Pros: really entertaing

Cons: not really any cons

I always provide one or two of these in my rabbits' cages because they are safe to chew and rest on. They also come in different sizes to accomodate your animal's living space.

Pros: safe

Cons: they are destroyed easily

Bunnies love these. Every bunny's house should have at least one. Great for chewing and digging, and you can place them over areas where your bunny tries to chew the carpet!

Pros: fun, promotes natural behaviors of chewing and digging

Cons: you'll need a replacement soon

My bunnies love grass mats!! I dole them out sparingly so they continue to think of them as a treat. I don't think that one lasts longer for a week in my house.

Pros: fun and tasty

Cons: none
