Rodents are extremely popular pets all over the world. There are hundreds of types of rodents. I am going to talk about those rodents that are popular in Europe. First of all in pet-shops we can see white mice and rats. So what can I say about them? These animals are really rather clever and quick-minded. What I love about them is their activity. When provided with a large equipped animal case they become very frisky and playful. They are very funny. But what I do not like about them is their tail, which I find rather disgusting. Unfortunately rats and mice live only two years or three at the most. But as they multiply very quickly, one may not grieve too much over the death of a mouse. Still there are not so many people who prefer to keep mice or rats.
