A friend of mine asked me once about my favorite animal. I study biology – how can I have a favorite animal. There are so many choices. The kitten next door, the penguins, the tigers, the koalas are all very cute. Even in the lab, when we look at some microorganisms they seem so full of life, so energetic and always one the move. How can a person not like animals? I had a cat for thirteen years. I love cats. My neighbor has 2 dogs. How can I hate dogs? A friend of mine has a snake and 3 big spiders plus an iguana in his home. And they are all beautiful and deserve to be loved.
