I love it when they give kisses. Funny though, I cant stand dog kisses. I guess I am not a dog person.
Sidney is our only licky kisser. He doesnt just lick as if it were the salty taste. And I have offered him a saltine to see if he would lick off the salt. But he wont. So I figure Sidney must be giving real kisses. He does this most when held in a room away from other GP cages. If you pet him just right he talks and licks every once in a while.
Occasionally he even does something I think is an immitation of the kissy sounds we make when kissing his fur. It sounds almost exactly like the sound we make, and he is the only pig that does it.
