Hi Maren, Petco went form exclusive MF ferrets to regional preferences ( cost cutting measures I presume). Very recently the local NH PETCO's here have switched back to MF from Triple F / Canadian due to temperament issues. Unfortunately that is NOT the only change in Petco re: ferrets... oh I wish they would stop selling them. Locally no longer can folks try to re home their purchased ferrets thorugh PE$TCO... and a NEW POLICY regarding the Petco Foundation and financial grants-- the new policy will be overseen by another agency for PETCO. The new outlines state that they will only support "stand alone " shelters meaning as far as I know , NO ferret shelters will qualify for monetary assistance through PetNO. Just one more unfriendly action to ferret rescue caretakers they burden. Alicia at www.ferretwise.org [Posted in FML 6404]
