Why are lizards the best pet to have? Lizards are the best pet to have because they are easy to take care of. They are like taking care of a fly because all you have to do is clean the inside of the cage, clean the decorations you have in the cage, and change the food and water. Also, make sure you change the water about every week or so. Speaking about food for lizards, make sure you give the lizard the food it needs. Also, some lizards like to watch T.V. or look out the window or even roam around the house, and some even like to go on walks. Personally, my favorite thing about having a lizard for a pet is when they hang on your clothes or go on your shoulder. Last but not least, did you know that there are over 4,675 kinds of lizards in the world?!
