Kimberly, I don't know about the pig's ears, but there are special chews for ferrets. NPIC makes N-Bones Ferret Chew Treats in chicken or seafood flavor. They are long, thin edible but hard sticks. It says "All natural, totally edible" min crude protein listed as 35-40%. Many places have them for sale, or you can check out their website at www.n-bone.com I'm sure a kit would especially welcome the chew treat, althought they also nip for play. They can be taught not to, but the chew alone may not help with the desire to play bite. Dooks Risa [Posted in FML issue 4497]
