How do you deal with an 'on the way out' pet?

Thanks for all the sincere replies. I have taken notes from all that was said and come up with my plan.
To preserve the dignity of my 'friend', I won't do Animal Humane or SPCA. You have to 'surrender' your pet first. And I won't ask a friend to do my dirty work. I'm not that schmuck.

I'm going to choose the vet and the two injections. Painless and humane. I doubt if the perfect shot is any better. Then I'm going to bury 'Lily' in the nearby National Forest. Yes I know it's illegal. Arrest me.

I did think about just releasing her into the forest. She is a totally indoor cat. That is why she made 19. Outdoor cats don't live long here. Anyway, releasing her seems cruel, but on the other hand it could be a last taste of freedom. It's tough to reason this out.

Just my opinion here, handle it like you end up deciding, but one is a sure thing, over and done quickly, humane (as possible) and within your human control.....the other is not. My mind can think of so many things that could do her harm if you release her. MY thinking is she doesn't deserve a possible "bad" ending.

But again, it's a decision only you can make and I certainly don't judge no matter which way you choose. It's a personal decision.

Oh and Kitty said maybe get on Google and do a search possibly in an adjacent state for something more reasonable. It's just a thought.
