the current cage im using is 16x12x24, i use care fresh and fabrics in the cage, as far as toys go there is a couple of tubes a hammock and igloo and a chew toy, i clean the cage once a week just cleaned it on friday, ive only had the rats for a couple weeks havent "deep" cleaned the cage yet, when i do, ill use a bleach solution, i have 2 female rats, havent given them baths since they smell okay.
maybe i just have a real sensitive nose, its not that the odor is foul, i just don't want any odor at all especially when i have guests over
