NATURAL, UNTREATED & GLUE-FREE
It always drives us crazy when we see someone selling compressed corks (imagine the corks from your favorite bottle of wine!) as bird safe. Compressed cork are small crumbles of cork that are held together with glue that we would never, ever give to our or anyone else's bird. Yes, they are cheaper, but cheaper normally comes with a price. So if you see corks being sold that don't look like one solid piece, please be careful.
CHEWY, ADDICTIVE TEXTURE
Birds always seem to go nuts over cork. It squeaks when they chew it and it's just downright fun to destroy.
