When I moved about a month and a half ago, we took the cats over the night before the big move to have them acquainted with the house before everything was moved in. We went to check on them and eventually had to put them in the main bathroom for the movers to bring the furniture in. What I didn't realize was that under the sink area was a water heater with a big hole behind it. Whisper, the gittery one of the three, figured this out real quick and refused to come out from behind the heater for about seven hours. For a couple of hours, I thought he had escaped and I was in tears for most of that time. I checked one more time behind the heater, trying to bribe my kitty with food, and his little head popped out from behind the heater. He still refused to come out but at least I knew he hadn't escaped. After I came home from work, he was finally out and happy as can be. Cats are very wierd creatures..just give your kitty some time and I'm sure she'll love it.
