We are taking a new approach to the Sassy/Sadie war. We have locked Sassy up in the living room and she will stay there for several days. It was suggested that each cat be rubbed down with the same towel; first one cat, then the other, repeated several times a day. Sassy will use Sadie's food and water dish, Sadie will use Sassy's. Sassy cries when she's locked up but I don't know what else to do. Sassy has a huge living room, toys, food, water and a litter box. She has the bay window to sit in and a side window that opens. Sadie has the run of the house. I took Sadie down to the litter box in the laundry room, closed the door and sat on the toilet while she explored. It took less than five minutes for her to use the box. So, she knows where it is now and can explore every room but the basement and bedrooms - only because we can't get her out of them. Eventually she'll have the same run of the house that Sassy does but for now, under beds and behind photo props are off-limits.
Today is my husband's birthday so we'll be going out tonight. Sadie will have the house to herself since Sassy will still be locked up. Perhaps her confidence will increase. And in a brighter note, our female bluebird laid her first egg today. She could lay up to five, one each day, and then she'll start to incubate them. Unfortunately, we won't see them fledge, we'll be gone.
