I bought one for Juni last year, the one consisting of two parts. She used in the beginning only for nr. 2, which is stupid, because it was good esp. for nr. 1. The liquid goes through those bars and the paws are dry. Well, can you explain that to a kitty? Then she started not using it at all. Only the old one, which is falling apart already. I have to buy one more, although the one I bought last year is like new. Still, I can't just remove this one, I tried, she doesn't use the new one.
That's a big question. What to do? I hope I'll figure out somehow.
