thanks guys guna try the mod

I believe there is mod that does just that.

for a vanilla solution there is this knife made out of tin... they stop existing and thus dont make noise anymore.

advice for later, have their pen/doghouse far away from your normal area of operation or location you want to be tranquil.

did not test it after H&H
