Old Fart And Young Squeaker

[GuineaPig24]

Bacon is much older than Sprite, but whenever they play together, Bacon-
1. Nibbles and bites Sprite's bum.
2. They "purr" and bacon rubs the top of his head against Sprite's lower cheek.
3. Their fur fluffs up and it is frightening.

We don't want a boar fight! Help!
