cats or dogs

If you had an option of owning a cat or dog which option would you pick? I would no dobt about it pick a dog over a cat any day. But I am sure that there are many people out there who would pick a cat over a dog.
One of the most major reasonos why a person would pick a cat because of a dog is because they are not as much to take care of. You can go on vacation and leave your cat at home but not your dog. The reason why I would choose as dog is beacuse they make way better companions!
