It does not say so on the package but I feel sure it is, Wood shavings are a byproduct of the lumber industry. The raw wood is kiln dried to eliminate shrinkage in the final product.

I just measured the bag, it's pretty big. I came up with 8in. deep, 17in. wide, and 24in. tall. I hope that helps. I'm a rabbit dad myself.

I would think it would be. I have seen it used that way in a farm supply store for the chicks to wallow around in.

Yes, it is very safe for hamsters. I use Aspen for my own hamsters, and have for years. Aspen shavings are 99.8% dust free during hamster movement ( not when changing or stirring the cage) and they burrow and dig through it with no issues at all. I have 2 wooden houses in my hamster tank and they always dig around the house and bury it in the shavings. All other wood- especially soft wood creates too much dust to be safe for hamsters, who often have respiratory issues. And please only use the 99.9 dust free bedding for the bedding in their house (looks like ground up brown paper bag) Don't use the colored paper, or use any of it for the bedding of the entire cage. But you can't do any better than So-Fresh Aspen shavings for hamsters.

Absolutely!  I’ve used it for all my snakes, including corn snakes. 

Aspen is safe for mice. It is economical and can help with odor control. It can be dusty but I have not found this to be.

Hi mpboston, Yes, it is. Thanks,

Hi Albino gecko, Yes, you can use it for crickets. Thanks,
