I am asking the question whether euthanising a cat with sodium pentobarbital is genuinely painless. When this drug is delivered to humans in 84% of cases their lungs fill up with a frothy liquid which causes pain and distress indeed panic because it is like waterboarding torture. How do cats feel when this drug is delivered to them? And can the syringe be positioned accurately enough to avoid causing pain? Please click on the link above photograph for more on this topic.
