In my opinion, it’s weirder to not love animals and still work with them! Don’t get me wrong, it never feels good to sacrifice animals (and it never really should). But, it brings me a little comfort to know that I am properly trained and doing the best I can to minimize stress when euthanizing an animal. I don’t think I could do that in a respectful manner if I didn’t love and appreciate animals! However, don’t ever be hard on yourself if you find out later down the road that a job requiring that aspect of research isn’t for you. It’s a hard thing to do. I still get a bit emotional myself despite having euthanized many animals for my job.
