Behavior Butt Sniffing?

[nikkialex]

Maybe this is a silly question but I'm still trying to learn my new piggies' behavior. During floor time (and only floor time) if one of my girls pees, the other one will sniff the pee, lick it, and then sniff the butt of she who peed. Is this normal? Or healthy? Is it a dominance thing? I'm trying not to worry myself over it but I've never seen another animal do this! (besides dogs, of course)

Totally normal, totally healthy. One's probably in heat.

Mine do this too. Didn't know that it could be an indication that one is in heat. You learn something new every day!
