I hear footsteps on my flat roof (London semi) in daytime. They seem four legged. Too heavy for mice, squirrels and probably rats. I’d say it sounds more like I would expect a cat or fox to make.
Cat I don’t mind (as long as it doesn’t get hurt).
Foxes I’m really not keen. But can foxes climb? There’s no scaffolding nearby that I can think of. And are they active in daytime? I only hear them at night usually.
Any other ideas of what wildlife is on my route? There’s no visual clue.
