If the poo is dropping from a bit of height into water the shape may not be the same as a poo done on dry surface at close range .
Is their any undigested food in the poo to give an idea of the diet of the critter ?
Can you take it to a wildlife refuge or zoo to be looked at by staff ?
Can you get access to a video surveillance whatsit ?
Can you set a trap abd catch the varmint ?
Thats all
