Description: This poo, which had a diameter of more than 5cm was placed on iSpot by Puggywug on 21/3 and the suggested identification was homo sapiens. However last weeks Hereford Times reported that a "panther like creature" was seen the following day [22/3] about one and a half miles away from Croft. I don't know what large cat poo looks like so is this just a coincidence?
