Super cute!!! I think you should get her a buddy though rats really hate to be alone and its so cute when they cuddle up together. Smell shouldnt be an issue if the cage is cleaned regularly and its an appropriate size. I never have never smelled my rats even holding them their fur doesnt really smell like much of anything. I have them on fleece and they use litter boxes with carefresh bedding and I just empty and refill boxes twice a week.
