This is for my gerbils Orlando and Sam. I took a trip to PetsMart today and picked up some more bedding and some gerbil food a wood chew and some tubes!
I attached the bin cage and the 10-gallon tank together and its awesome!! I didnt realize how narrow the tubes where until I brought them home, but gerbils are pretty swift and stream lined. They have been running back and fourth between the cages.. Here are some pictures.
I havnt had tubes since my first hamster when I was in elementary school. FUN!!
