Ok. I have a new coast cage that Splinter and Tweezer have been living in a couple days. I love it. It's nice and roomy, they love the wheel, and Splinter LOVES the concept of ramps and shelves. I still have the 10 gallon aquarium that Splinter lived in. Is there some way to combine them? I was thinking about cutting a hole somehow in the side of the cage, and cutting a hole in the aquarium cover, and connecting them with a tube.
