i like cats. they are usually small and furry
I love cats too! My favorite breeds are the ones with soft long fur, They can sometimes be a hassle to clean though. 
they have been used to hunt vermin and are often used as companions for himans
Yes but I believe most people have them as pets more often today than they did 50 years ago. 
There are many then 70 cat breeds . What kind do you have?
