Hi
I have two female cats, 1 is 9 months the other is 11 months. Both have been going outside during the day while I am work for the last three months. They currently have two indoor cat litter trays, but ideally I would like to encourage them to only use these at night when they are indoors. When I next clean the litter out can I put some of the old litter out in the garden where I would like them to use ( I have a row of conifers which I think will be an ideal spot as its private and sheltered) as a toilet? Will they smell the litter and go to that place?
