THE K9 VS. THE FELINE:
Dogs can have a lot of advantages when it comes to safety. Most dogs will bark and alert you of intruders. You are also able to teach dogs tricks much easier than cats. However, dogs are very social and require more attention and time than owning a cat.
Cats are a low-maintenance companion. Most cats are quiet and independent. Cats don’t have to be taken out several times a day, but you will have to clean a litter box.
One is not better than the other. When most people get a pet, it depends on their lifestyle, because there are pros and cons to every pet.
Hopefully this at least got you started!
