A few years ago, my indoor cat with no front claws, got outside. We tried to find her. This was in the winter time. The next morning we had a real cold spell, 30 below, didn't get above zero for a week. I put adds in the paper ect but no kitty. Well after a week, I was sure she was dead. The next day it got above zero and the sun was shinning. I came home from work, and there was my baby sitting on our front steps. She headed right to the water dish and drank and drank, ate a little. Didn't look like she had lost weight. I asked her where she had been, but she never did tell me. She is now happily playing in kitty heaven.
