However, I would not even consider euthanizing a pet at home using any other method than
anesthesia overdose. It is the only humane method, in my opinion. Let me explain this procedure.
When it is time, I settle down on the bed or the sofa with a nice, plush towel for the rattie to be comfortable on. I pour some Halothane onto a couple of cotton balls that have been placed in a clean and empty small baby food jar. I put the jar in front of the rat’s nose. Halothane is not unpleasant, but the rat usually moves away from the jar at first. After moving it back in front of the rat’s nose, he often sticks his nose into the jar and, in a short amount of time, just falls asleep while I am petting him, talking to him, telling him how much I love him, and making him feel completely comfortable. Slowly, and not afraid, he goes to sleep.
Once asleep, the rat needs to continue to breathe the Halothane until he stops breathing and his heart stops. To ensure that he has definitely gone and his heart does not start again, I leave the jar in front of the rat’s nose and walk away for about ten minutes. This method has been a comfort to both me and the rats I have used it on. It is never an easy decision to end an animal’s life, but I am at peace knowing that my pet did not have to suffer, and was surrounded by love in his last moments of life.
