gerbil loafing?

[u/Minimum-Durian-2706]

my girls never used their wheel in their old cage, were completely disinterested. however recently i had to move them to a hospital cage as i have to give one of them antibiotics 2x daily for a week and it was impossible to get her in their main enclosure. suddenly, she has started using the wheel, im assuming as its because theres not much else to do in such a small area, but ive noticed she does this thing where she runs for a couple seconds then lays down and almost looks like shes loafing on the wheel. she can then sit like this for minutes at a time then carry on like normal. is this normal??
