The use of resting platforms by young silver foxes ( Vulpes vulpes)

According to the current European recommendation for animal protection regulations for fur animals, farmed foxes should have a resting platform in their cages. Therefore, the total time of use and factors affecting the use of resting platforms by 20 young silver foxes were studied on an experimental fur farm in western Finland. Silver foxes used the platforms on average 70 min day −1 (median 24 min day −1). The use declined over time from September/October (146 min day −1) to January (9 min day −1). Interindividual differences in platform use were marked especially in September/October. Platforms with a more unobstructed view of the surroundings were preferred to platforms with a more restricted view. Platforms were used most during the working week, but outside the working hours. Neither daily temperature nor wind velocity had an effect on platform use. It can be concluded that platforms function neither as protection against cold and draught nor as a hiding place. The role of the platforms as a resting place is not supported by the short and decreasing duration of their use as a function of time. They may have a role as a place for making observations, or simply as an environmental enrichment.
