Tipping over Pigloo

Question
My two guinea pigs have a plastic igloo we call a pigloo. They enjoy sleeping and hanging out in it but they frequently tip it over and go potty in it making a mess. Do you have any ideas for training them to stop this behaivor or any suggestions on how to make it unflipable?
    Thanks So Much!

Hi Tracey

It was long ago that I tried stopping my pigs from tippig up their pigloo or doing other similar things. Pigs will do what they want to do and there is little we humans can do to stop them.

My advice would be to try to keep the pigloo in one place by using heavy objects such as brick.
