Hi, thank you for the information. I do have a couple of questions.
1.The cat litter in the box "clumps together" when she uses it. Would it be worthwhile putting some of those clumps in a spread-out area of the garden where we put the tray to deter other cats and help her identify her area?
2. We live in the UK and its incredibly rainy here, the litter in the tray will turn into 1 solid lump after a rain shower so Tasha wont be able to use it. I wonder therefore is it better to just mark out an area of the garden and mix the content of her litter box with garden dirt?
or wouldn't that be as effective? I cant see another way around putting the tray outdoors.
