I have had my piggy, Maui, for 5 days now. He is about 2 years old. He is a bit skittish but will let me pet him. I let him smell my hand but will sniff and then give a little nip. He also will walk up to me during floor time to sniff and nip. Is this a normal behavior? It never hurts (so far)! He takes food from my hand but runs and hides when I enter the room his cage is in. He also has growled at me once while I was carrying him back to his cage. Should I be worried about the nipping? He has yet to popcorn which makes me a little sad he isn?t happy yet. Thanks all!!
