I have two cats names Sam and Dean
Are they house cats? Do they have any distinguishing characteristics? 
yeah they are two tabbys
I know that cats are also valued for their companionship and their ability to hunt vermin.
I have heard that they can pick up on our emotions'

I guess that helps them since danger early
Yeah they can also see in near darkness
That is really cool I had no idea they could do that!
If you decide to breed your cats, you would have hobby known as cat fancy
