hey guys i have a imac fantasy with extension kit for my syrian hamster but i feel like its too small for her and my parents wont let me buy a new cage so a am going to connect a bin cage to a imac cage , i know you need the connector plates (i think thats what they are called) but i have no idea where to get them from.
also can you use critter trail tubes on the connector plates or does it have to be the ferplast tubes?
