You're not a wuss or a baby and it's completely normal to feel badly sometimes. I've fed off literally hundreds of rats and I still hate, hate, HATE feeding off the cute chubby and still blind fuzzies. For some reason that still bugs me as they are so darned helpless. Pinks, pups, weanlings, smalls...don't bother me at all...but darn feeding fuzzy rats just makes me feel bad a bit about the whole thing.
