While growing up I had all kinds of family pets including Dogs, Cats, birds, Guinea pigs, squirrels and fish (salt and freshwater)
Each has it's own appeal, but I really love dogs for their loyalty and sensitively to your moods.... (hmmm I also love that in a BF)
Cats when you DO win their affection are also wonderful, faithful companions.
When I was a kid (13-14) I had a favorite huge black and White kitty named Tinkerbell (HEY I didn't name him!) that followed me everywhere, would sleep on my bed until I was asleep and return just before wake up time and would purr and rub against me to tell about his affection. When vacationing about 50 miles away on an Island, my family could not find him when we left for home... I was devastated and cried looking for that favorite pet. One week later, a very hungry. skinny black and white kitty showed up at our door... I have no idea how he got home but I was so happy!
