RE: What if your pet grows and grows and grows ...
That is one cute piggy! Though I have to wonder if they eat bacon, and if they do, if they feel guilty eating it around their piggy pet. I am glad that, once they decided to keep it as a pet, that they didn't turn it into bacon once it started growing. (Although I love my bacon!) I wonder also if their pig is within its proper weight range or if it's overweight. I have no idea what pigs need for exercise, but if it lounges around the house all day, that can't be good for it. I hope they will consider giving the pig some exercise.
I did think that the last photo looked unsafe for reasons stated above. That's a lot of piggy to roll over on you -- a bad chance of injury or even death.
