Jaffa was feeling left out with Mosi vomiting (furballs) so decided to join in. Unfortunately he was in his little house in the cat tree. So the inside of the house is covered in vomit. It's fake fur fabric (walls are cardboard but I don't think much has gone on the sides). It doesn't come apart and there is just a hole at the top and the front. He has, of course, been sick in the most inaccessible corner where I can hardly see it, let along clean it up. What will work best on fur fabric? I've got most of it up with paper towels but it needs a proper clean and I'm struggling to reach the corners. Any suggestions?
