My bastard cat has a thing about the sofa (black leather, imitation stuff but looked all right until he started), one corner of it particularly, and has clawed it so badly that the stitches have burst. It looks awful and I can't turn it round to hide it as the room's too small. Can this be repaired, and how much would it cost, or can you buy something, like an adhesive leather patch, to stick over it? Has anyone had this problem, maybe this thread would be better in the Litter Tray, as it's a common cat annoyance, I know.
