Humans don't understand why we do the zoomies. No, I don't mean that boring computer stuff. I mean when we take off and run madly round the house or garden. Frenetic Random Activity is what scientist call it!
Sometimes we do it just because it is fun to work off surplus energy that way. Sometimes we do it when we are playing with another cat. Sometimes we do it because it gets the attention of our humans, who laugh at us. Sometimes we do it the same time every day, because the daily routine has sort of space for this kind of thing.
But.....
Sometimes when we zoom away from the litter tray it is because we want to get our paws away from that disgusting mess. Human hygeine can be very thoughtless. We want a litter tray that is cleaned at least once a day and preferably twice. Or even more often.
We don't like getting our paws wet with damp litter. We don't like an overwhelming smell. We want out as soon as possible. So we zoom away to shake dirty litter off our paws.
So clean up more often, you human servants.
