a big old rat toy!! made this for my ratty tatties as they were getting a little bored with their tubes, and as it says, it is just made of a dog rope, little cat jingle balls and a coconut...and some wire...they LOVE LOVE LOVE it as i stuck little treats in it as well, so, there you have it...and it only cost £2.50 at the most, these things sell for about £9.00 in Pets at Home!!!
