I am sorry that I have upset you.
I don't believe that reptiles heal faster because they want it more.
I do believe that some species are better at adapting to captive life than others, and that view has nothing to do with caring or not caring for different types of animals. An example of what I mean is something like an orphaned wallaby enjoying being raised by a a family, and being able to socialise happily with them, or something like that.
If you can successfully rehabilitate injured reptiles in a short amount of time and it can actually go back into the wild as a reproducing member of it's population (which is good for accidents, not so good if they were just genetically weak and not meant to go on and reproduce), then great. But I was more commenting on the animals that can't be rehabilitated, are too weak for anything natural, and need to be kept, and it is being done in an illegal manor. Wildlife carers will hopefully know when a case has a high hope of success, and when to PTS. Vets may or may not just treat the animal if the customer wants them to and is happy to pay.
I do care about all animals, that is why I think about things like this. Some people seem to think that the only way to care about something is to keep it alive at all costs, regardless of quality of life. Sometimes it is more humane to PTS instead of prolonging suffering. I respect the efforts that other people put in, to support what they believe is right though, even if I don't agree.
I commonly get into debates with people in the rat world who catch/"rescue" baby wild rats or even adult ones, and want advice on how to nurse them and where they can release them LOL. My advice would be to PTS as it is a pest, and give a home to a nice pet one that likes being held instead of wanting to chew your face off and disappear. Or debates with people who want to retrain genetically extremely aggressive pet rats, or medicate really sickly rats that have incredibly scarred lungs and are deathly skinny, to get a few extra weeks/months with them. The people get upset and tell me I don't love animals and I am so nasty, because every animal deserves the right to live as long as possible, regardless of the quality of life.
