Don't risk your pets life with this bedding. Just cleaned my son's guinea pig cage and while putting in the new bedding I noticed several items that don't belong. Large pieces of white plastic bag or wrapper with red lettering 1" slices of frade green plastic rope 2 cubes of cut wood with white paint on them I'm going to guess this is why one of the GP has been so sick. We will be throwing away the rest of this bag and will no longer use this brand. I've sent a message to AWF and won't hold my breath. Again, don't put your animal in harm's way with this bedding. Ingested either of the three items I listed could have been deadly to my kids GP. not worth the weekly savings. Switching brands today.
