Maybe if the Bobcat started eating with the cats when it was a kitten, it don't really know its different. Might have been an abandoned kitten. I live in the city and we have a pair of Fox's that just had pups. They live a half block off Main street. They don't even run from people or cars. Just saying, anything is possible with wildlife.
Everyone's a genius. But if you judge a fish by his ability to climb a tree, it will live its whole life thinking its stupid.
