License fees of cats
The cost of pet ownership is high enough. This especially so if you have multiple cats. Mine all stay indoors so why should I have to pay for a license. It's not as if they are being walked in the park like a dog. When the big guy goes out, he is on a leash and is supervised. If you let your cat roam free, he should be microchipped or have a break away collar with identification. Better to keep them inside away from the traffic and people who would harm them. This way you will have them for a long time.
