Boy can I relate, 3 yrs ago we got a very tiny siamese female kitten. She was good at first although tiny so we kept a small litter box upstairs, until our other female cat started using it and wheweee. We went with just one covered box in the basement and showed her where it was. She was good for a while. Then we went away for a week and she choose the corner by the front door, we used every different cleanser and deterent and nothing working until we put in a noise machine in that corner, that worked for quite a while, then she choose another corner, same routine,moved the noise machine. So far so good on that, however we have to be very careful with laundry and she will hit both the dirty hamper and any clean basket left around. She is such a sweety but we are going away again this Fri for 10 days and I'm afraid if she is bad again she will have to go.
