Hi, I'm sorry for your injury and bad time this am, and all before work! I agree that cats should be kept indoors, or, if outside, then confined with a kitty harness and leash or one of those cool kitty tunnels that I've seen for sale. Cats that roam are vectors for bringing diseases back to their homes. You are also correct that cats are responsible for decimating native bird populations, including songbirds and game birds. I am fortunate to own a large wildlife refuge where my seven dogs and I can walk off leash so when they see a big healthy fat housecat they can chase it up a tree without me getting dragged behind. No, I do not encourage them to go after any animals but sometimes the cats catch us by surprise. We have a feral cat group in our area that traps them and releases them after neutering them but all the cats I see on my property are someone's pets. If I let my dogs run loose like that, someone would call the sheriff right away! Good luck on resolving your serious cat issue. Prayers that your injuries heal quickly.
