This is quite funny. Cheddar is *assumed* under a year old and has only known aquariams as a place he has called home. Now he is in a ferret cage with tubes that run up and around the cage. He has braved the mighty climb (rather small) up the tube and I came home to find him inside the tube, afraid to get down! lol. I'm letting him stay, hoping he'll learn to climb down, should I do that or how long should I wait? Don't want him to stay up there forever!
