From one human to another I want you to know that you did great. You responded with care when those kittens needed it the most. I don't even know you, but I know that we could be friends, just by this one act of kindness.
The part about 2 kittens showing up after a little kindness reminded me of the children beggars here in the Philippines. You give one of them a few pesos and the next thing you know, you have more children asking. Those kittens definitely did some communicating with each other.
You seem to be like me. All tough like on the outside, but gooey on the inside. Even being a non-lover of cats, you are still human, whether you want to believe that or not. Although the world seems to be going to crap at times, there are still plenty of us kind and sensible human beings left to keep things in perspective.
If it were me that rescued them, I would keep them to control the mice, roaches and other bugs around here, but you don't have that option. I'm willing to bet that you will do your best to find a good place for them to live. Hopefully both of them together. I'm also sure that you will have your wife's 100% cooperation (because if she hasn't found out about them already, she will eventually) in finding them a good home.
In conclusion, I'd like to say that this world is a better place with people like you in it. You continue being you, even with your tough guy exterior. It's part of you and what makes you who you are. Thank you again for being a good man.
P.S. I hope those kittens didn't leave a little pool on your pool table.
