Hmmmmm
My CRPS is a stoat or weasel....cruel and viscious in that way only those creatures are, hurting for the sake of it, and totally without charm. Skulking in the cold and dark and waiting to pounce, attacking without provocation or need. Terrorising other creatures, taking over an area, competing for resources and driving out less viscious creatures from their territory. And unable to be controlled or eradicated....
A bit dark I know, but right now (it's not been a good couple of days

) that's how it feels!
BTW, I'm not including ferrets in here! They are cousins of the above, but have a different temperament and are not harming ecosystems in the same way.
