I have a strong opinion on this: euthanasia for pets
I have had to put to sleep several pets during my lifetime for one reason or another. It was always difficult. First to make the decision, and second to actually do it. Only one pet we took to the vets. The rest we did at home. I would like to see a euthanasia service where someone would come to your house when it was time and quietly and calmly administer the medicine while your pet is with you and in his/her favorite place. Going to the vets is so traumatic to my animals that taking them there for their last time on this earth is not my choice. My fear for starting such a business is people would randomly use it just to terminate the lives of unwanted animals and that would not be the purpose. So I do not think it would be possible. :(
