Instead I brought Rustan and Natasja, both wellbehaved and extrovert, so there were no problems.
I didn't make them run the ferret race, as I felt they really wouldn't like it. They didn't this autumn.
When we came home, Roxane jumped more than she's done for months, so it seems she didn't like being "left at home", in spite of having company of Alison and Carmen. I guess she's really fond of Natasja.
