We have an elderly cat who has taken to using the immediate garden as his loo. Currently dh is clearing away the number twos most days but the garden smells and we have to avoid a big chunk of the garden (we have a small dd I don't want playing in 'poo corner' as we refer to it). It wouldn't be quite so bad if it was in the border and very edge of the garden but it's spreading further out into the grass and taking up a large area as he varies where he goes,
I'm on the look out for an outdoor covered litter tray for him to use to make it less smelly and so we can use our garden without fear of poo or poo remnants in the grass. I've googled this online and found a few that come up that look like they would work when I type in 'outdoor cat litter' but when I look at the info they don't necessarily say they are specifically for outdoor use and the reviews are often people who use them inside.
