I’ve recently got a new Guinea pig (Barry) and my other one (comet) is not happy. Comet will get jealous whenever I’m holding Barry. Today I had held Barry and afterward I held comet and he started going crazy. He kept on sniffing my hand and clothes and quietly chattering his teeth, wherever Barry’s scent was. He also would lick my exposed skin. Is comet being territorial? Do Guinea pigs usually do this?
