Jen, you owe it to yourself to at least give it a try. Granted, it may not change the behavior but then again, it just may. It would improve the quality of life for your cats and more importantly, for you. People first. Some may not agree w/my people first philosophy but if it wasn't for you, your cats wouldn't have the wonderful home that they do have and your fosters wouldn't stand a chance. You won't be able to continue like this indefinitely; your home will become unlivable. It's the last line of your post that got to me: one day, there may not be such a good outcome. You're feeling the squeeze and no one doubts for one second how much you love your cats, fosters included, but you have to love yourself more. Several PTers have offered to help you w/the cost of a reading w/Nancy, so that objection doesn't hold water now. (Sorry, couldn't resist it.) And it isn't silly if it helps to resolve the problem. Give it a whirl. You've got nothing to lose and everything to gain.
