I've had two piggies in the past. They were both incredibly tame and sweet (and they were both abyssinians). The only thing I would suggest is just to keep on socializing with him I spent A LOT of personal hands on time with my piggies so maybe that's why they got so lovey. Either that, or I was just lucky to get two oddly friendly piggies

I'll see I can dig up some old photos of them. They were such sweeties. Cuddles, the male, was primarily black with a white band around his middle. Cream Puff, the female, was white with a cream colored patch on her bum

I'd love to see photos of all your piggies! They're defiantly one of my favorite animals

Oh yeah, I had a harness as well! Lol, they weren't much for walking though. They mostly just liked to sit around and nibble on grass

Well, good luck! I'm not sure how much help I was, but I just can't resist a post about piggies!
