For 20 years I owned a marina in Florida. I had three dogs and two cats, and they came to the marina every day. Four of them were rescue animals.
One of the cats, named "Hobie Cat" greeted all the fisherman when they came into the dock. He would hop aboard and check out their catch. He learned which fishermen were consistant in their abilities, and soon didn't bother with the ones who never seemed to catch anything.
During a particularly noisy thunderstorm, one of the dogs tried to escape the noise and climbed up some steps to the attic. Part of the floor was unfinished, and he stepped there and fell through, landing on the desk of my secretary. Fortunately, no one was hurt, and she had a good sense of humor.
Hobie Cat was very adventurous, and one time decided to check out the UPS truck while the driver was making a delivery. The driver drove off with him, only to return a few minutes later when he discovered his felline passenger.
Our customers loved our animals, and often brought their dogs along. They all seemed to get along fine, and we never had any problems.
