What is euthanasia like for a senior cat?

Euthanasia would be us as veterinarians easing the passing of said cat, or maybe not easing, but causing the passing. There are drugs that we use injectably that, there's no polite way to put it, but that will stop the heart of a cat. And obviously in their life, that way it's very humane. It's very quick. It's very peaceful. It is quite literally an overdose of an anesthetic. So there's no pain involved with it. It's just, again, when we know that an animal (a cat in this case) is at the end of their life and there's nothing else we can do, there's no point in allowing that animal to suffer and to die a long, drawn-out, painful death. There's no point in that at all. So it's our responsibility as veterinarians to ease that suffering. And that's how it's done.
