I'm so sorry you lost Cuddles, and it was a horrible experience for you.

When I had to put my cat down, it took more than one injection, and he was moving around & meowing, it was very upsetting to watch. I don't know if they underestimated how much it would take or what, I know they had a hard time finding a vein, but he was so sick, I knew it had to be done. The worse part is wondering if I did the right ting, but I look at it this way - Yes, he did seem to have a few minutes of pain, but if I had just let him die on his own, he could have suffered for another 24 hours or longer. Actually the vet said it could take days longer-- he couldn't move, eat, or drink, so it would have been agonizing for him & me.

Know that Cuddles is at peace, and would want you to remember all the joyful times you had together.
