That sort of trust should be rewarded with belly rubs and by finding all their hard-to-reach itchy spots.

There was a cat that lived behind a job I had years ago. It was a mean little shit and wouldn't let anyone near it without hissing and running off. I was a smoker back then and I guess me being out there smoking everyday and just not bothering the cat, It learned I wasn't a threat. Eventually It came and chilled next to me on my breaks, then after a month of that finally let me pet it. The cat would still hiss at anyone else that tried to pet it but me, was pretty awesome.

If nothing else, it means they haven't had too many bad experiences with humans, which is nice.

I love it when cats on the street come over to be petted. And how my own cats are like "oh, you're finally home, give us food now and then you can fuck right off, I'm going to sleep"

Best part of my day every single day is being greated by my dog when I get home from work. The little midget waits for me all day and comes to life the second I pull into the drive way.

They probably smelled the lunch I spilled on my shirt and couldn't clean up entirely

Can't relate.
