When we got a new kitty, he would disappear and we cold not figure out where he was going! One night DW opens a can in the kitchen, and I am setting on the couch, and hear a rumbling! Out comes kitty! He had pushed his way through the gauze covering the bottom of the couch, and made himself a little "kitty cave" gues to get away from the other cats!
That's what we were thinking they had done. But we turned over literally every piece of furniture in the house and got underneath the beds with flashlights to look. We checked under the dressers, in every closet (in the unlikely event they squeezed under a tiny slit in the door), under the fridge and stove, opened all cabinets, behind the washer/dryer. You name it we looked and our house is only 1 story and not that big! Plus, we had shut all the bedroom doors before we let them out. But we still checked the bedrooms. I even checked the load of laundry I had put in the washer & dryer and in the dishwasher! Although I'm not sure I would have wanted to see that.
My sister killed her first husband's childhood cat. It was right after they had a big old fight, he had left and she was doing laundry. The cat had jumped into the dryer while they were fighting and she turned the dryer back on later to warm up the clothes and remove the wrinkles. Needless to say the cat did not survive the Permanent Press Cycle!


Anyway, as long as the kittys are inside I'm happy. They are just too little to be outside in this cold weather, plus we have not introduced them to our other animals yet and I really don't want the dogs leaving dead kitty's on the doorstep for me. We wanted to get them calmed down and used to us for a week or two before we attempt that.
