I have a phobic revulsion to any insect that jumps (and can thus land on you,) stemming from crickets and grasshoppers and extending to cicadas and whatever else looks like them. Something about the tactile sensation of them landing on your skin, and then pushing off from it rather than just crawling or flying away (the long rear legs with big thigh parts is also a problem, nixing house centipedes and their ilk, but not millipedes.) So wetas are right out.
I like standard cute, but I also find things that most people think of as ferocious as cute, particularly with big dogs, which many people shy from, where I always want to tackle and roll around with (my dream is to own a Tibetan mastiff, which is basically a dog that put all of it's character creation points into "lion," allegedly pairs of them have killed tigers, the only primary source of which on the English internet is this: http://www.wayangtimes.com/rich-chinese-woman-pays-more-than-us500000-for-rare-tibetan-mastiff-dog.html , and I think they're they cutest things ever.) Like, you know, bears are good. Angry horses, especially in person, which is frightening to think about because they can easily kill you.
I also think giant isopods are adorbs, which is in no small part due to this shirt design by Jeph Jacques: http://theoystersgarter.com/2008/08/14/because-i-happened-to-have-a-giant-isopod-in-my-office/ (the thought bubble says, "I feel pretty,")
(Also, apparently no longer available from QC? how do I tear drop emote?)
