Not all cats can live inside. It's not a matter of being responsible, sometimes it's just not possible to take very cat into your home. I have four cats in my house. They were all strays at one time. I have usually no less than six others living outside of my house at any given time. I make sure they have water, and I buy nutritious food for them to eat. Although they are free to roam, or even leave whenver they wish, I still call them my cats. It is just not possible for me to take every stray that comes around into my home, but I still have compassion towards them, and give them a place to stay, and good food to eat. Yes, sometimes bad things happen to them, but that's the life of a stray. If you feel that I am not being responsible then go ahead and deride me.
But I will say that I know how you feel CadetLee. I hope Jake makes it through okay, and I'm glad your other buddy turned up.
