Cats seem to avoid shitting on the bike shed roof - probably because it's where they like to sleep.
Squirrels do like to bury things there though - walnuts, acorns and the odd whole egg (shop bought, as you can see the datestamps. Fuck knows where squirrels keep their wallets though.)
Foxes like to shit there occasionally - I'm guessing when they feel very athletic.
And there's been the occasional big bird crop (I'm hesitating to suggest a owl), with bones and things in.
Really like these, exciting to follow your progress.
