I know, but that one is cute. As Missy has quite possibly met any one of several violent ends, it is possible you might get a better cat out of this. If anybody calls and says “I haven’t seen your orange cat but I did find a black and white one with its hind legs run over by a car, do you want it?” you can politely decline and save yourself a costly veterinarian bill.
I knew someone who had a basset hound that had its hind legs removed after an accident and it had to walk around with one of those little buggies with wheels. If it had been my dog I would have asked for all its legs to be removed and replaced with wheels and had a remote control installed. I could charge neighborhood kids for rides and enter it in races. If I did the same with a horse I could drive it to work. I would call it Steven.
