answer:Ply her with treats. First start off by giving her a treat when she comes up to you. Then follow up by giving treats each time she lets you pet her for 10 seconds. Move it up to 30 secs as you become more successful. With a shelter cat, you will need to build trust. Once she understands you will always give her food, water, shelter and love, she will willingly be open to showing you affection. With some cats this process takes a few days, with others a couple of months. We took in a feral kitten last Spetember. At the time, she climbed the windows trying to get out of the house. She now follows me everywhere like a puppy.
