Little poor kitten was left totally alone. A woman found her and get her home. Personal experience tells me that the sick, the troubled and unsterilized animals no one will take. For the simple reason that to treat it will have a new owner.
So, before you attach the cat (dog) was found on the street, you need to cure it, allow in the “commercial” view, to sterilize. If you leave the house such an animal you can’t (you are not allowed parents, husband, relatives), take care of a foster home for a pet.
Overexposure is a temporary home for the animal where it is fed, like if you need to, walk, etc. And for now this cat starts to recover.
