So for the last month and a half I have been feeding a cat that I have seen on my block often. I set up a little box with blankets on my porch that the cat sleeps in and she allows me to pet her, she rolls over , she purrs, overall she is a very friendly cat. She still gets a little skittish if I move to fast towards her or sometimes when I first start to pet her. This morning I decided it was time to bring her to the vet to see if she is actually pregnant and to get it shots and spayed. When I went to pick her up, she wiggled pretty fast to get out of my grip, and without thinking as she was trying to get away I grabbed her leg. She hissed at me when I did this and so I let go. When I tried going near her she just kept going away from me. I left to do some errands, and when I came back the good news was that she was back. My question is what do you think the best way to try to capture her might be, and also do you think that in time she will become to trust me again? My biggest concern for the cat is to get it spayed so it does not produce more kittens that will become feral. I would eventually if I do get to take her to the vet and the vet clears her of any possible diseases make her an indoor cat, just like the two I have now. Any adivse on what to do , and what no to do will be much appreciated. Thanks
