I'm sure that every single one of us as a new glider owner has their own humorous story of their first glider escape. This is not going to be your last either! I will try and give you some advice about the liner though. I only put newspaper in my liner pan, nothing else and I change it every other day. I tried the disposable potty pads and also the fancy bedding but a lot of gliders will eat anything and can become blocked from just a small amount so now I don't risk it. My boys weren't big enough to reach the bottom at even 6 mths old but they grew into that ability before a year and I can frequently hear them scratching the paper or see them reaching down for some dropped treat. I have to be sure the paper is flat or they grab hold and try to pull it through the bottom. Also you have to have a good hand vac or a dog! I made a cover for their cage that blocks 3 sides and contains a lot of the mess. My dog eats the rest of whatever falls on the floor. Use this site to search for any questions. I don't think there is one that didn't have an answer.
