I love all animals but i'd have to say cats.....from lions and tigers right down to pet cats. They're just such beautiful creatures. I've had cats pretty much all my life and cant imagine being without them (i currently have 3).
Dogs without a doubt. I have never not had a dog by my side. When I was born there was a dog there that treated me like her puppy. She watched me grow up. I recently had to put er down and even typing this tears come to my eyes with how much I miss her.
I have such a weird thing for bees, they're just so interesting in terms of their behaviour and I'd love to keep them some day Plus I find them kinda cute.
Other than that, at college we had some giant African millipedes which are another of my favourites; they were so much fun to handle
