The problem with social media is that anyone can say anything and it's often impossible to say what's useful information and what's garbage. I haven't tried joining any Facebook animal groups, but I've perused a couple and seen a lot of terrible advice. Some of it's outdated, some of it's nonsense. I'm in Canada also and the prevailing wisdom seems to be that small animals are easily replaceable toys for children that aren't worth the money for vet care and as someone who has had rodents and small animals my whole life, that infuriates me. Once on a Facebook friend's post about her child's hamster dying, a friend of hers (not mutual, thank God!) commented on how they got their kid a hamster with the promise that the child would feed it and give it water, and when the child didn't keep up with feeding and watering the animal, they let it die to teach the kid to be more responsible! Like... you let an animal die horribly! I didn't respond to this stranger, but I actually cried... I have hamsters too and the thought of either of them starving to death and dehydrating in misery breaks my heart.
