I've been bitten by nearly every mammal I've ever had, though I don't think my bunnies or skunk ever bit me when I had them. For herps, I've been bitten by a ball python (definitely my fault) and a crested gecko (clearing dirt out of her mouth with my finger -- only knew I was bitten because I saw it). Kitten bites are worse than the bite I got from my 4' ball python, though.
