My pet rats also did the "weird swaying thing" with mine it precipitated going to the bathroom, it was very strange but when she did it I always put her back in the cage, she would go right away. I have seen my ferts do it on occasion as well but I have never seen the same actions afterwards twice so I don't know what it could mean. I think maybe they are trying to hypnotize us "give us raisins, raisin soaked in ferretone" My two fuzzbutts have become increasingly free range over time. They are only caged at night now. They have free run of the livingroom and kitchen. They do see the cage as home because it is still where the majority of sleeping and pooping takes place. And for my laugh of the day My fiance stayed over for a couple of days with her Guinea Pigs, we cape a cage for them at my place stored for when they travel. Bob was having a big war dance fit with me chasing him. The chase stopped right in front of the cage with both pigs looking intently at the action. Bob chose that peaceful moment to turn and look at the pigs. Once he realized he was being watched he went right back into his war dance as sent the pigs fleeing under their blankets, what a laugh it was. Mark Bob and Marmot [Posted in FML issue 2495]
