I noticed several of us quilters have cats so I want to ask a question. My daughter has a one year old cat that had a litter of kittens in Sept. The Weds before Thanksgiving we took the kittens from her and had her fixed. For the past few weeks she has peed on my daughters bed everyday. I don't think the problem is physical because she has not peed anywhere else in the house. Any suggestions on how to get her to stop doing this? Thanks!
