I use to have a mouse colony before I just got tired of cleaning up after them (got pretty large actually, almost twenty moms). I killed all of those cute things and now I have a bunch of cages. Notably four ten gallon tanks and a twenty.
Obviously the twenty can hold a lot of snakes, but are there any snakes that comfortably fit in ten gallon tanks? I don't think I'll fill them with snakes for a while, but in case I do.
