I have a cavy, Emmett, and I'm getting him a bigger cage. I'm also getting a new cavy. I want to use Emmett's old cage (It is in very good condition) for the new cavy while he is under quarantine for a couple of weeks. If I clean it out well, can I use it or will his scent stress out the new cavy? Should I deprive Emmett of his well deserved upgrade and give the bigger cage to the new cavy?
