Take them in , and have the Animal Control pick them up for rehoming as they are young enough that they have a chnace at getting Furr Ever Homes.
Its a shame these Crack Heads have your phone number.
I pray they dont have your address.
I hope that the Animal Control takes thier Other Cats too.
I have this in my neighborhood, all the time and am feeding at least 4 Porchies!!
Please keep us updated and they are Dear Little Cats.
