A poor craftsman . . . God is obviously shite at tool use. Probably needed a few more years as an apprentice before he started fucking around with firmaments and stuff. I mean hacking together a whole human out of cutoffs? Just pony up and order more stock, cheapskate.
I think that really depends on the individual, some rats are skittish and don’t like being handled at all. The best way to handle them is to leave them alone.
Humans should test their shit on themselves or on some other human that they can explain the risks to and agree compensation.
