They mix their male piggys with the female piggies. its really bad, their poor piggys have baby piggys over and over, no rests. I feel sorry for them, im glad i rescued dear scruffy.
That should be illegal to continuously breed the piggies. Scruffy is a cutie! I am sure she loves the reprieve from the mass orgy at your neighbor's house. She looks albino in the pic cause of the red eyes. But I guess it might just be the camera & lighting. She's adorable.
