Fluffycat is a 6m old long haired breed cat. She’s using the litter tray to poo a few times a day but then spending ages digging and scraping at the litter and the tray, which often results in dirty paws. We had a covered tray initially, we’ve bought a stupidly expensive self cleaning one as I was cleaning the old one several times a day to make sure there was nothing in it she could stand in accidentally. Her poo is soft and absolutely stinks, I read that the problem could be her food. Does anyone have any advice on how to discourage the excessive digging or otherwise solve this problem? Our other cats have never done this.
