Our rabbit used to love this as a treat. It made his cage smell nice and sweet when we'd open up a new bag.

Our chicken's vet suggested we give her some of this too, but she had no interest in it.

Pros: Delicious

Cons: messy

My guinea pig can't seem to get enough hay. She likes to burrow in it if given the chance. :-)

Pros: great addition to diet, fairly inexpensive

Cons: can't think of any...

We give our rabbit timothy hay every week. It's great for her digestive tract. We have a little ball that hangs on the side of her cage and we keep it filled at all times. They hay smells so good that she runs right over when I fill up her ball. Highly recommended!

Pros: Great for them

Cons: None

We used this in our chicken's nesting carrier. She moved it around until she'd made herself a nice comfy nest, but every so often she'd kick a lot of it out onto the floor and then it would get very messy. It smells like fresh cut grass when you first open the bag.

Pros: Good nesting material

Cons: messy

Our guinea pigs loved to hide under this. It was a mess on the floor, but they had a blast.

Pros: hide in it, taste

Cons: none
