I'm off up to Newcastle in a minute, so I might do it in the car on my nifty handheld PC
didn't see any whole dead cats, about 6 whole birds, lots of patches of feathers but no torso, and lots of odd little bits of legbone here and there
I put it down to being a rubbish tip, rather than an unusually active local chapter of satanists, but you never know ... as long as they wear high-visibility clothing and hard-hats, I don't see a legal problem ...
Health and Safety, never fuck about with that ...
