Just that really, how often do you?
We have 2 big male cats and 1 litter tray, mainly indoor cats and I’ve never seen them go to the loo outside.
I scoop the poop as soon as I see it, and do a total clear out once a week as it was starting to smell.
I’ve just cleaned it out and immediately both of them have gone and used it so I’m thinking maybe they didn’t want to go when it was so dirty? Should I be changing it more?
We use catsan litter if that makes a difference!
