Hamster-powered ventilation system? Answered
I'm in the process of expanding my hamsters cages and because of the design, I'm not able to leave the top open to allow better air circulation like I'd prefer.
The cage is made out of plexi glass with ventilation holes on both sides and I found a post somewhere about using a computer fan behind one end of the cage to increase air flow. Is there any way to wire it so it turns on when the hamster runs on the wheel/at a random time?
