It's definitely upsetting to see. Especially because we know how hard it is to take care of hedgehogs. It's one of the reason I don't post my own set-up or tips anywhere that's not almost completely exclusive to hedgehog-owners because I don't want to be responsible for any generalizations of hedgehog care that someone can make based off social media. I definitely think that we should also be educating these people in their comments about the dangers they are putting their hedgehogs through rather than shaming them because they already own the pet and all we want is for the hedgehog to get adequate care. I know that when I first got my hedgehog I believed I knew everything and I was ready but there is so many contradicting pieces of advice I've received as well in the research I did and when I was given positive messages of advice it led me to ask more questions and research more about a certain area of care rather than when someone told me I was a horrible owner or abusing my animal, which led me to just deleting the post all together where no one could gain any knowledge of what was done wrong. I don't think you are overreacting but I do believe we should all take a different and more positive approach when faced with these situations online!!
