That's just stupid, and cruel. Instead of giving people a fine, why don't they get the people who feed the cats involved in some kind of trapping and neutering scheme, I'm sure they'd want to help if they're cat lovers.
It's the same with any council, never put the publics money to good uses just line their own pockets and fine people for stupid reasons. No doubt the mayor and police chief have very cosy offices with everything they need. They should try taking in a few cats and give them home.
You're right that is thoroughly annoying
