3 black kittens

These three black kittens and their mother was on your house porch, the mother feeding them until she saw you. her and her kittens are blocking the doorway to get into the house and they have a cat bed on your porch as a nest they are all in. (Theres a tick bush nearby. Theres a neighborhood.) The mother does not like you. The mother is very defensive. The mother(yes, its still a cat( me talking to talkie systems).) The mother thinks the territory she is on is hers now. What do you do? Also, kill them for all i care.
