OHHHS.
Lol
Well, I do have fun building different little houses for gerbils, but they don't always turn out too beautiful. xD I made it out of a box, it's three levels with holes and stuff. :D
Oh that does remind me, I built my hamster a little shelf she could climb up onto with a ladder leading up to it out of popsicle sticks, and a little house with a ladder leading to the top of it too. So I guess I did build those things. The gerbils only get cardboard creations because they chew everything up too fast for me to spend TOO much time building them something. xD
But they have fun climbing and chewing the things I make them so win/win.
