Chico, your Tux is always on my mind. For now, he is getting fed twice a day, so he's not going hungry, which eases my mind. If and when I can even touch him, I can better gauge if he will allow me to grab him.
I think if I do get him inside, and let him have the kitchen, I can see the gangs reaction to him. At the very least I can keep him safe inside, and try to get him to an adoptable stage, if the gang don't accept him here.
It's so hard.
I was though able to find a couple of places that neuter at low cost. One is $55 and the other is $15. I think the latter would be my choice. That is done at the county shelter.
