I've looked on Google and manatees aren't very winsome in my opinion, although perhaps baby ones are.
Those badgers of yours look like they've checked into a hotel, not a wildlife centre. Looked at the website. The animals are gorgeous - loved the baby fox.
Isn't it weird that baby animals really appeal to us, yet we are less gooey at the young of our own species? I think human babies are OK, but I always feel vaguely guilty and bored... I used to feel the same way in church. Perhaps it is punishment of some sort
