Getting a pet is a big decision, almost as big as deciding to have a child. If you get a puppy or a kitten, it will need constant care, attention, love, exercise, feeding, and cleaning up after. An animal is not just a doll that once you get tired of it you can just leave in the corner. You need a stable life to keep a pet happy.
Once you decide that getting a pet is right for your lifestyle, consider getting an adult pet at a shelter, one that needs your love. Going to a kill-shelter will help save the life of an animal.
Once you have gotten your pet take it to a good vet clinic to get it checked over and have all the appropriate shots.
