I would honestly rather be bitten by every snake in my collection than get scratched by my stupid cat. I've gotten bites I've barely noticed and one that actually hurt. I think it really depends on where you get bit. Getting bit on the arm or fingers doesn't hurt but getting bit on the palm of your hand does hurt some (especially if it's a large female that does it). With snake bites it's more of the shock factor, afterwards there is a little blood and that's it. Their teeth are super sharp so it's like getting a shot. A little soap and water later and you usually can't even tell you've been bit.
Rodent bites suck. >_<
