Snickers...

I was wondering if you can connect tube to the cage "here & there home and traveler". It has a little hole at the top, that is blocked by a piece of plastic. And if you can connect tubes to it, does it have to be a certain name brand of tubes? If you have this cage, please help me out.

I wanted to get a hamster now for a while, but my parents say "NO RODENTS!" I don't get it because I am very responsible. I am on the honor roll at school, and I always help my parents around the house. Its not like i'm begging them to buy it for me, I am going to use my own money that I earned from doing chores. Also, I would defiantly not treat my new hamster as a RODENT! I would treat it as if it was a new member of the family. I would even keep it in my bed room so they would have to be bothered with it. I promised to take care of it all by myself. Please if you have any advice to help convince my parents to let me get a hamster, let me know. Thank you.
