If you have ever owned a cat which likes to spend a lot of time outside, you’ve probably wondered, exactly what is it that they do all day?

The secret life of cats is one of the great mysteries of our time, and I’m not saying that every feline sneaks away to a part time job as a bicycle inspector, but I mean, take a look at the evidence for yourself.

This scrupulous bike check, conducted by two very committed cats went viral on Japanese Twitter, with one user even calling it ‘the strictest bicycle inspection in Japan’.

Everything must have seemed in order with this particular bike, since the two inspectors walked away in the end, leaving the bicycle owner with a renewed confidence in its safety.
