I don't really go for animal names either, but I LOVE Leo (if that name counts, maybe Leopard "Leo" or Lion if it doesn't count?). Linnet is also fine, close enough to Linnea which I like. Elephant maybe for a MN? I haven't thought about it as a name before but I think I have a new GP :P
Other suggestions (I'm going wild here..): Llama, Jaguar, Lark, Hawk, Heron, Nightingale, Raven, Seal, Tiger, Wolf, Zebra, Llinos (means greenfinch), Mavis, Sparrow
I don't even know if I could call some of them "names" :P My favorites are by far Nightingale and Wolf. Any other suggestions?
