Great advice!!!! That exact same thing has happened to Silvia and it was VERY scary!
My DH and I were outside talking to the neighbor, and I came inside first and then he and my neighbor came in maybe 30 seconds behind me. We have two huge saltwater aquariums, and it was time to feed, so our neighbor wanted to watch. After we thaw food and feed the fish, it probably takes us about fifteen minutes to do so. When we were through feeding, my neighbor opened the door to go home and Silvia came running in from outside!
We hadn't even noticed she wasn't inside, and we never saw her go outside. She must have heard voices outside and gone out before the door shut behind me when I came in. We would have normally noticed her not at our feet, except that we were talking to the neighbor and showing her the fish.
We both freaked out, but thank God she was OK. So many things could have happened, because she is so small! Apparently she just sniffed around the carport and the flowerbed. We don't live on a busy street, but our front door is only about fifty feet from the road. We were so blessed that she was apparently scared to adventure far!
Now we MAKE SURE that she is inside everytime we come in or go out.
