I have been thinking about getting a "Teacup" Pig. But I hear everyone adopts them thinking, well they will be like tea cup poodles but NOPE! I have to share this pic: lol!
Some are actually small pigs. Will they fit into a teacup? No, not as adults anyway. All of my adult pigs are 40 lbs and under. The picture you posted is a potbelly and an obese one at that.
