since our inside bords can't get to little gravel and stones out side grave is a must to be suppoied for them. they need this to break up the seed tey eat. my sheet would over do it so i would have to likit her she would scoop beakfuls at a time so for her i switched to gravel paper where she would have to pick it off

Pros: great for digestion

Cons: some birds will over do it

We use this gravel in our bird cages. It helps with the digestion and helps keep the cages cleaner. The birds do throw it everywhere. :)

Pros: easy to use, works great

Cons: none

Baby Birdie occasionally eats the gravel but for the most part it sits untouched. I guess they use this only when needed.

Pros: Reasonably priced

Cons: none

This helps with digestion and my parakeets loved it. I would recommend it for any small bird!

Pros: Healthy

Cons: None
