A cat needs to explore the world around her, if you restrict her, it will make her either fearful or furious wandering cat. A well grown up feral cat cannot be adopted as it has not been in contact with any human so it could be distrustful, scared or aggressive. It is suggested to adopt a kitten having age of less than 8 weeks. It would be easier to tame, train, handle and socialize her with the home members and other cats.cat-colonySource: catster.com
