I am a 14 year old soon to be rat owner. I'm just working out the kinks with my rat plan and finishing up convincing my parents. I am SUPER excited. I will be getting 3 boys along with a critter nation single cage. I have been researching almost a year now. I do have one problem. I need to know how much fleece to by for the pans. If any critter nation owners out there could measure their pans or tell me how much fleece they buy to cover them, that would be great!! Thank you!
