If you haven't had a pet I think that you should start with a hamster or a guinea pig, these animals do not require much help and are fun to watch too.
There also are cats that are very friendly like Blake, a little kitty who is cute, cuddly, friendly, and LOVABLE! Cats always take time to adjust to our schedule, like sleeping during the night. The first night with your pet you might need to comfort her or him and make sure everythings alright.
