I had a house cat a while ago, but haven't had one in a long while.  It was an indoor only cat.  Do you have/like cats?
I'm more of a dog person.
I like them both.  It's nice to have something that can hunt vermin for you :P
I guess that would be useful. Are there different breeds of cats?
There are!  There are more than seventy breeds of cats recognized by registries.
What tactics do they use to hunt their prey?
Mostly stealth, using their flexible body, quick reflexes, and sharp claws to take down their prey.
That's so cool. When did humans first start domesticating cat's?
I don't know for sure, but probably at least ancient Egypt.  They were valued for their companionship.
