Update on this: I got one of my racks Wednesday and picked up the tubs yesterday, so I've let the breeder know I'm ready for her. I'll move my three into the rack this weekend and then I plan to use Calypso's old tub to house this girl (I've already named her Tessa) in quarantine. I already bought a small pack of rat pups with my last order of rats so I've got everything I need for her.
