we don,t have the mink around we used to have , i think its because of the numbers of otters we have, i just got my first mink job in 2 years at the weekend on a local pond, i set both fenns and bodygrips 2 days ago ,nothing yet but i,ll get the buggers, all traps for mink should have a drowning wire on, just incase its not a perfect catch, i don,t use cages as i think they cause too much stress to the trapped animal, i have had loads of mink over the years with broken teeth and nails ,sometimes thou you have no choice , like gardens with pets and small children
