How to Domesticate a Semi-Feral Cat?

It will take more than a few days for your new stray-cat to get accustomed to your presence and other people. If you don't want to wait for your this cat you can also release it(it will back again it wants to) since most cats are able to take care of themselves. If you worry to much you can take it to your local Animal Department,or SPCA. You've had your own cats you are not obliged/have to look after what you can't afford to look after.
