I just notice that the heating vents on the floor are just wide enough between the slots for the budgie foot to go into. Skyler was walking around chasing a ball and he got close to it. I never would of given it a thought if I didn't see the heater vent and him beside each other. They are sharp if you stick your finger in them. So I hate to venture a guess on what it could do to a leg and foot that got trapped in it. Just a heads to anyone this would apply to.
