DIY Wood Agility Bridge
Construct a ramp for your guinea pigs or other small rodents! Cut wood blocks for the bridge supports. Cut a piece of wood to lay across the blocks and cut pieces of wood for the ramps on either side of the bridge. Carve grooves across the top of the ramps and bridge, and paint each piece of wood. Attach the ramps to the bridge with hinges and glue the bridge onto the blocks.
