Plastic Bottle Hamster Tunnels

Make tunnels to keep your hamster entertained and active! Heat plastic bottles to bend them into any tunnel shape needed and cut off the neck and bottom of each bottle. Secure the bottles end-to-end with strong tape and consider having a dead-end with a bottle that still has the bottom attached. Poke many holes along the top and bottom of the tunnels for ventilation and experiment with varying sizes and shapes of bottles to create an elaborate hamster tunnel playground.
