I'm sure the people you share a boundary with are delighted she's digging up their garden to
tit in. Always nice to be doing a bit of gardening and come across the
tit of an animal you don't even own.
When we were kids our neighbours had 5 cats that would
tit in our garden. If my Dad found it he would drop it back over the fence. The neighbours had the cheek to ask him to stop.
I said it last time this topic came up. Cats should be kept indoors, or have access to an enclosed catio. I don't want your animal's
tit in my garden, or the holes they dig to leave said
tit.
