I should explain that this is the Accidental pet pig. Not that we would have had a pet pig, and we do have normal pigs so he has company, he just prefers humans.
He is very clean. We often leave him indoors whilst we go shopping never have to worry about him, and he keeps the dog company.
For anyone considering a pig as a pet they are easier than cats, dont shed, dont scratch the furniture (although he does eat cushions given the chance) dont spray, and now he is bigger doesnt climb on to laps. Ours sleeps in the barn at night.
And yes those farts are obnoxious. Never have him indoors after he has raided the hen house for eggs!!!!!
