That is exactly why I had male rats. I wanted snugglers. :) Cosmo used to curl up with me to watch TV. He LOVED when I wore a hoodie with a pocket, as he would curl up in there and snooze.
I have to say, though, that it was fun to have two different clans with each sex. The boys were great for cuddles. The girls were a riot to watch literally bouncing off the walls. xD They would all pile into the wheel and try to run at the same time, which resulted in gerbils falling on top of each other. Crazy little things! They also loved to climb the wire portion of their cage, so I played the game of "which gerbils will be on the cage walls when I walk in". It was always a safe bet to guess Pi would be on the walls. I am pretty sure she thought she was part bat, as she would even hang from the top sometimes!
