Dry wood was the most preferred resting place and icy sand the least preferred resting place. Different floors were chosen for activity and rest. The wet or icy floors were chosen less often as a resting place than for activities. Dry wood was more often chosen as a resting place over being an active place. Dry sand was twice as likely to be selected for active behaviours as for resting.
Foxes are individuals too.
In other words, different individuals preferred different floors. The researchers believe foxes have a low priority for flooring in general, but a high level of priority within individuals. When blue foxes were tested for cage furnishings preference the same individual consistency was seen. People assume that if an animal picks a resting place and decides it is uncomfortable then it will rest elsewhere next time. The foxes in this study mostly chose to rest on the same floor area as where they had finished their previous resting period.
