Superpet Tropical Fiddlesticks in the large size is a very versatile product. Basically they are long round sticks of wood connected by a thick wires running through them so they can be bent into lost of shapes. I’ve used them to cover part of the wire floor, or roll them into a tunnel, or arch them into a large house. You could bend them into stairs, use them as a ramp, or put in some hanger bots and have a nice size shelf. They measure 18″ x 10″ and are brightly colored. Each wooden piece is about 3/4-1″ thick and Fiddlesticks are made of a harder wood so they last a long time.
I have this for my chinchilla, and he loves it. He uses it all the time; I have it folded up as a tunnel house. Before the sticks I had a hay bungalow which my chinchilla had chewed a hole through, and didn’t care for much. His go-to hiding spot was underneath his wheel before I got the fiddlesticks. I just bought a new chinchilla and when I finally get them bonded there will be plenty of room for them to snuggle together in it.
