We’ve designed our Kitty Fresh box and litter to last one cat one month when scooped daily. However, we recognise all cats are not alike. Older cats, bigger cats, or cats with health issues may need their box changed more frequently. Once you’ve subscribed, if you find you need a more frequent delivery you can change to every three weeks by Contacting Us. You can also switch to a less-frequent delivery of five or six weeks if you have a very small cat or a kitten. We’re happy to customise your subscription to suit you and your cat!
