I want to keep a pet , but I don't know which one to buy ?   Dogs are nice , but they are really energetic , and you need to make sure they get enough exercise every day .   Having a dog would probably be too much work for me , then .   What about cats ? They are more independent .   Actually , I was thinking of something a little more exotic . I don't want a common pet like a dog or a cat .   How about a lizard ? Are lizards more along the lines of what you were thinking of getting ?   Yeah , are they easy to look after ?   Yeah , they are pretty low-maintenance ; they eat almost anything .
