One of my friends messaged me the other day, drunk out of his mind. His cat that he had for 15 years was at the very very end of its life, with probably only a few hours to live until it succumbed to cancer. It was in extraordinary pain and discomfort. He tried bringing it to a vet for euthanization but it was against their policy to accept checks and it was too late to visit the bank and too expensive to withdraw from an ATM. Without other options, my friend felt forced to put the cat out of its misery himself and submerged it in a bathtub. It twitched once, but put up no struggle at all.
