This is a fun and easy toy that will keep your rabbit/chinchilla/guinea pig occupied for hours! Grab an old toilet paper roll and poke holes all over it. Grab your pet's favorite flavored chew sticks and place them randomly around the roll.
I tried this with my bunnies hutches with irrigation pipe and drilled holes in it to filter out the pees and poops. The rabbits absolutely love it! Its nice and dark and they just chill in there as they see it as a safe and spot.
