My guinea pig keeps knocking over his igloo. does he not like it? should i take it out?

my guinea pig does that when he has too much energy, maybe you should take him out and play with him for 10 minutes next time he does it, get some energy out of him. I put my guinea pig outback in the grass ( and closely watch him of course) to stretch his legs, get some fresh air, and eat some grass. Hope this helps=]
