Pigs if left  on their own to live freely as nature intended are extremely clean and very intelligent animals my Grandad had thousands of them that were turned into sausages and various other things . They use bits of piggies to feed and repair us the human race of various ailments and somtimes people are called pigs which really is an insult to pigs and not the humans which are normally far more dangerous , that dirty and evil than the poor pigs they are being compared to

Pigs can be potty trained.

I have not owned one but they are said to be very smart & trainable.Despite the name,clean and fiercely protective.As I recall they are also good around children.These pigs are as domesticated as any dog or cat.
