Interesting article, but as a vet student I can say this probably won't be a success. This might be worth it if you want to keep your expensive horse alive to breed with it, but the number of people that would pay sufficient money to give their cat a prothese is close to zero.
You don't let the vet do a surgery on your goldfish either, it would be much cheaper to buy a new one. A vet isn't a doctor who will save his patient no matter the cost, that's the sad truth of being a veterinary.
