We had gotten a bag from either petsmart or petco and it smelled weird. I took it back and got a refund.
To me it smelled like cedar, I could be wrong, but didnt like it.
I now go to our local TSC(tractor supply company)we get a big bag and its from Premier Pet brand name. Big bag for under $10.
I get my mice wood pellet bedding there and now that I looked around..I get my dog food from there too.
So it is real nice to go to one store and get most of the supplies I need.
Snakes, mice and dogs supplies and they are cheaper than the pet stores too.

So being cheaper in price, all in one store, I save on gas too.
It is a win-win thing for me.
