my sister left us her 3 cats before she moved out. we left them in the back because pops is allergic to them. so what happens next? they start poppin kittens like crazy. the kittens are very scared of us, or used to be. i would say just keep on feeding them and get along with the mother. keep feeding and petting her. then later the kitten's will see that then they would probably give in; most likely. they know you got food, they will come begging for it being all friendly and shit.
