Feeding the cats back blip

Our neighbor Edna has cats. All are feral. She says they are descendants of the many cats the lady who owned our house had. There is a small black cat and a large tabby type cat that come out of the woods sometimes to eat scraps we through out. They are rough looking to say the least and hide in our barn from time to time. She only ever had one cat of her own and it sadly passed away several years ago. She has tried to tame kittens over the years with no luck. Once she caught one and had it in a basket in the house but it also passed away. There are only 3 at this time. She thinks the coyotes caught several last week. Sometimes life on this ridge can be tough. She has caught the cats and had them taken to the shelter but new ones show up and she always has a pan of cat food for them. I believe the woods are full as people have told us Mrs. Richmond had over 100 cats.
