My cat won't go in
I have it on a terrace, I bought two, but the entrance is small and my cat is a large breed, he doesn’t want to go in. I’m not sure if it’s because he doesn’t fit or because he’s scared by how small the entrance is. So he does his business outside. The best thing is a covered litter box and try to put it somewhere where it doesn’t get too much rain on rainy days. Also, tape up any ventilation gaps it might have. Because this litter box is a big contraption, it takes up a lot of space but the entrance is narrow.
