Lethal Injections.

I see that the question of sourcing of chemicals for lethal injections in the USA has arisen again.

There is one thing here which is worrying me a great deal.

When vets 'put an animal to sleep' - is it suffering or isn't it? - If veterinary chemicals cannot be used because 'animals suffer being euthanised' - we have all been conned a great deal over a very long time.

If the animals do not suffer - then where is there a problem? - Let the authorities use veterinary chemicals.
