In the last few weeks, a mother cat and three kittens have begun living under my nextdoor neighbors porch. I'm not sure how old the kittens are, but they seem to be atleast a few months old. I just bought some kitten food & started mixing it with wet food and put it outside for them. They're still afraid of people (and my dog) and run under the porch at any site or sound of people. My mom (who is allergic to cats, so we can't keep them) says I shouldn't feed them because they'll start depending on us and breed even more. She's also afraid that they'll still hang around the house when I go back to school in the fall. They're too skiddish to trap and we don't have a low cost spay/nueter porgram in the area. I don't want them to be hungry, though. What can I do?
