You are a great person for taking care of all of those feral kitties. I have one little feral girl that I take care of and feed. Someone must have fixed her and released her back here when she was very small, because she is ear tipped. She lived in my neighborhood for years, eating from garbage cans, in fact, that was the only time you'd see her, was rooting through the garbage on trash days. I would leave food next to the cans, and she wouldn't eat it. She would run. Then slowly, years later, we would see her sitting in the grass across the street, during the day. Then one day, miraculously, she took a can of fancy feast that I set by the curb. Inhaled it. Slowly started to show up every night around six for her can of ff. I slowly moved the bowl closer to my door, until one day, she was near the door, waiting for her can. She would hiss at me and then devour the food in 4 bites, and run. I started to sit in a chair, leave the food about 10 feet from me, and one day, she ate the food, and then laid down on the ground near me and groomed herself. This led to one day, about 3 months later, she started rubbing her chin on the side of the house, near me, and I could tell she wanted to rub against my leg, but she'd get close to me, and stop. I remember the day she rubbed against my leg though, happy day! It took months from that point before I could scratch her chin, and about a year before I could pet her. Now, more than 3 years later, I can half pick her up under her front legs, as long as the back ones stay on the ground. She sleeps in my garage during the cold winter months, but other than that doesn't want to come inside, which is jsut as well, I have 4 strays I have accumulated over the years, the last one being last February, when it was really cold. Took her in to "foster" her, and fell madly in love with her. One of my cats, the oldest, she is 11, is a beast, and can't mingle with the other cats without trying to kill them, so I have a "rotation" schedule, so everyone has fair times out of their room. I make it work, because I love them all. Yes, everyone that knows me says I am the crazy cat lady, but I can't help it, I just love them so much.
I have so much respect for people that do what you do, and help ferals.
