I would have happily gotten a $ 50 dollar license in Denver if they'd given me the option. Instead, they cited me for feeding the neighborhood ferals and insisted on searching my house. I managed to postpone the search until I could get my cats moved to other locations. And it's a good thing I did, because three animal control people showed up with carriers, ready to take my cats away.

Also, Denver is notorious for refusing to cooperate with TNR groups. I was in touch with a rescue group at the time, trying to set up a neighborhood TNR program, but the city wanted no part of that. They simply wanted the cats to die. Horrible people!
