We have a herd of 17 pigs soon to be 19.
We first bought four and now have eight in their cage. Someone is always laying outside of one waiting for the person inside to leave so they can take it.
Some of them like to move them around as tanks, or move them to the food dish so they can eat from underneath of it.
But so far they have all loved it I don't think we've ever bought a Hidey or a bed that they have loved more.
Now I just really want to get some blue and yellow ones.
