Give that a try. I have had other people use it with success. Just spray the bed and any other area she has gone a few times a week. You can test her with the bed by keeping a kid's pee pad on top of it when you guys aren't sleeping. I had to use those for Twig (my cat that died from bladder cancer) cause he was having accidents all over. They work great and are easy to clean. I got a few of them from Walmart for under $10 each. You should be able to find them fairly cheap.I think so.
