I'm sort of an animal lover myself. However, my favourites would have to be::
Owls - I don't have much of a reason, except they are cute [occasionally] and quite simply amazing animals.
Falcons - I've loved them ever since that time we had one visit our classroom because of Career Day. They're another animal that's simply amazing, in my opinion.
Pretty Much Every Animal In The Cat Family [I own three cats as it is =D] - I've never had a reason - It was an obsession that started way back in the times I don't remember anymore.
