My noisy neighbors have 2 small dogs (they had 3 but I complained so much about the barking they got rid of the worst one) and a skinny male cat. They had 2 cats but 1 disappeared. Monday their cat came over begging for food and he looked in bad shape. His left eye was swollen shut and he had scabs all over his head from other cats scratching him. Plus, he looked skinnier than ever. He was so hungry that he slinked past my cat to get to the door. My cat doesn't bother him anymore but he used to chase him. He looked a little better today but his eye is still messed up and he should see a doc. What can I do? I can't take him to the vet. I keep feeding him hoping they see me doing it and get with it.
