To the increasingly bewildering 23,539 Followers who read what I write here on Notes but haven’t checked out my actual newsletter:

In 2014 Dutch scientists left a hamster wheel outside, to see if wild animals would use it like their domesticated counterparts. The answer: hell yes! 734 visits from wild mice - plus rats, shrews, slugs ("running" being a highly subjective term here) & even frogs and snails.

The apparent reason: fun. Just fun.

If you missed this joyful thing, it’s possibly because you’re not reading my newsletter.

(But you’re clearly also not reading Brendan Leonard, because he wrote about it in his last book. Double FAIL for your brain there.)
