We often discuss this topic. In my opinion, Cats is better than dogs. I have three cats in Japan and they are three years old. I think cats is very friendly because they always follow me and sit down on my knees. It is so cute:) We sometimes sleep together, but they always went to somewhere when I woke up. In addition, they sometimes wake up me by riding on me. They slept together if I could not wake up. Moreover, they do not need to take a walk, so we would not busy if we have cats. Once I tried to take a walk for my cats because I sometimes see people who take a walk for cats. However, they refused it. That's because they do not need it. Finally, they are always in unexpected place. For example, on the shelf, in bed and the narrow place that usually they can not enter. I was always surprised. We have them in the house, but they often escape to outside, so we have to look for and catch them. However, this also cute point.
This picture is not my cats. I can show you picture if you want to see!!!
