These grass mats are a favorite with my rabbits. They love to sit on them, chew them and dig at them.
The only problem is they move through them rather quickly and they are somewhat expensive.

Pros: comfortable, edible

Cons: pricy

Both of my rabbits love the mat in their own ways. Macey loves to sit on it, and since their hutch has wire bottoms on the first floor, this is an excellent way to give her feet a rest! And my other rabbit, Keiran, loves to chew this thing to pieces. And it's still lasting us quite a while! Double rabbit approved!

Pros: both my rabbits love it

Cons: its not so big

These maize and seagrass mats were a wonderful find. They are incredibly popular amongst pet rabbits, and they seem to stand up fairly well to moderate wear and tear. I would say they are pretty versatile.

Pros: Affordable and practical

Cons: none

this is a really cool idea. my guinea pig likes to chew on it and it never hurts him!

Pros: my guinea pig lovs to lay on it

Cons: he moves it too much and cant get it how he wants it

Satisfies a rabbits need to chew and can also serve as a resting place.

Pros: Chewable

Cons: none
