I don't really have an intro to these guys, as they're just too cute for words!
They're baby fennec foxes, for those of you who aren't familiar with those large ears. The fennec fox lives in the Sahara desert, where they use those massive acoustic organs to both hear its prey from far away and cool off. It's nocturnal, and hunts rodents, insects and just about anything it can get its adorable little paws on. Interestingly, it's one of the only species of Fox that is able to be properly kept as a pet - just ask Jeff Corwin - but most areas require special exotic animal permits to do so. Of course, it can jump 4 times it's body length and dig 20 feet deep in a night, and can't be housebroken, so it's not exactly an easy pet to keep.
But, since as adults they're just over a foot long, they're absolutely adorable animals and it's no wonder people like keeping them as pets despite their difficulties. Also, to end on a positive note, they're not endangered in any way - I guess it's hard to kill off a species that lives where most of us wouldn't want to. If anything, deserts in Africa are expanding, giving this little guy and his prey an even greater range of habitat.
