We have something living / or has lived in the garden shed. We put some hay bales in the shed last spring and they've been there ever since. On moving them this week we have found poo which looks a bit like ferret poo - couple of inches long, and slug like - not pellets. There were feathers around where a bird had been eaten, and feathers made into a nest in between the lower bales - a space which a small cat could fit in. There is a hole at the back of the shed where the animal could get in and out. The dogs are very interested in and under the shed. We have just moved into the house after 18 months of rebuilding the house, so whatever it is could well have cleared off now the dogs are here. A dry stone waller working on the garden wall last year said he saw a black animal run across the lawn - a lot bigger than a squirrel but not as big as a fox.
We are fairly high up on the Yorks/Lancs border, surrounded by fields, no woodland to speak of, 1/4 mile from the nearest stream.
Any ideas?
