Encouraged by the raw foods people here on PT, i've started giving mine raw chicken legs, wings and backs. They do seem to love them, have no problem crunching them up, and it should help keep their teeth in good shape. prior to this, I gave them those sterilized bones they sell in the pet stores, and some smoked beef bones -- and Star broke one of her molars on them. The vet said once this happens, she should have regular cleanings to remove the tarter, because now it could get into her jaw & make her very sick. This will cost $$$$$ because she'll need blood tests & anesthetic in order to clean her teeth. So only raw bones from now on!
