Unfortunatly, most people think that they are different from everyone else. As in, you tell them that this animal will die if kept like this and they just shrug and think "mine will not be like that".
I have seen that problem too many times. I knew someone that used to feed their dog chocolate and I told them that chocolate can kill your dog. But she just said, "well my dog is different".
Some people... I think the problem is humanity has developed too big of an ego for being 'the most important creature on earth'. Most humans (even subconsiously) think they are gods and are not subject to other beings problems. Like when I say something like how, compaired to most animals, humans eyesight, hearing and smell suck. And someone always has to say "well, mine is better that all of yours". And it is like, no we are all equally human.
Sorry for the novel. I just can never complain about this because the person I tell this to will say "well I am different". :/
