Who, the judge?
If I were a kid and my best friend, my cat was taken away from me because of "some crazy old lady" next door, I would mad at her and my parents. After all, cats don't have to go out; they could have just kept it in the house.
The kid's mad at everybody, but can't take it out on his parents as they're too close, so he takes it out in a passive aggressive way with the complainant.
No huge deal, just a mistreated child who'll probably be screwed up from this for the rest of his life.
