My cat has always been an indoor cat. She sneaks out every chance she gets, but doesn't leave the porch. Occasionally I carry her out into the front yard. If a car happens to pass, she goes ape-shit scaredy cat. No way would I trust her not to run off (or be chased off) out in the great big world. Do you use a leash?
BTW: I used to be a sales rep in the flooring industry. Many stores were Mom & Pop shops, where the owners put in long days. Their businesses were literally their second homes. I always felt the nicest accounts had a dog or a cat who came to work with their owners. However, this same amity does not extend to customers who shop with their pets, especially at grocery stores. When I worked at Nordstrom, a guy used to bring his Bull Mastiff into the store. The giant dog always looked miserable, like the proverbial bull in the China Shop. Poor dog.
