Thank you for clearing up the confusion! I have not bathed them since I have had them because I didn't think they needed it but I had seen some people mention it on here so I thought I might have been wrong. I will just keep doing what I'm doing!(:
I only bathe them once a year in summer but even then only if they are particularly smelly that even a clean out won't sort it. (I live in a open plan flat so if they are smelly you can't really ignore it). And even then, I'd only do this is summer or warm spring days. They hate baths so I don't like putting them through the stress.
