Hey do you own any cats?  I used to but now I have a dog.
No, but my sister had a grey house cat called Mickey, he was an indoor cat
Ohhh how cute. They are good at killing vernom like rats.
Yes they are really valued by humans for their ability to hunt vermin.
Yes and also as companions especially for older people who are lonely.
Cats can also hear a lot more than humans, a lot of faint ant to high frequencies made by mice
yes they do.  Some even say they can detect spirits around the house.
Interesting, its probably the fact that they can see in near darkness :D
