For decades, foxes visited our garden occasionally, but last February, one would stand on our patio looking at us through our French windows for a minute or two. Then hop back over the fence. It did this for several days. We never reacted as we've always liked them. They never did any damage to our garden. It then seemed to disappear, until in late March we saw this. I guess she'd been sussing us out in February, to see if we would be a threat to her expected litter. "Dinner for six." She'd made a den under our Japanese Tea-House. I built it on low brick piers, so it has "skirts" on three sides, which don't quite reach the ground but at the back, I left it open for air circulation. So there was a gap of about 9" between the flags on which it sits and the base of the building. She had a litter of six cubs, all healthy and she was a very good mother. We didn't go in the garden when they were out, but I did supplement their diet with a can of cat food every night. They grew at an unbelievably rapid rate. All the photos and videos I took through the glass of the French Windows. All six cubs did well and she eventually took them all away, at the end of May, two at a time over three nights, over our six ft fences by way of the top of one of my Japanese lanterns. They'd flattened a few bluebells, lily of the valley and cyclamen and dug a few holes in the lawn, but it all recovered. I gave them an upturned box for them to practice their "pouncing." I used to put out some dried mealworms for them and the cubs would come right up to the French windows They were out most nights playing, setting off the PIR on the back of the shed. The light didn't bother them. We miss them a bit , but I've made sure we won't be getting them again this year.
