This morning, luckily my husband went out to the garden before I did. The Patio Family had brought back "food" again, and this time they left it right outside the patio.
It was another dead snake.
There must be a nest somewhere and I've already alerted the neighbours previously. Surprisingly none of the neighbours expressed any concern. One even said there cannot be any nest here and that's that.
My husband took a photo of the snake and he'll try and identify the species.
The Patio Family brings back dead lizards all the time and leave it at our front door. It's their food offering to us and their way of saying "thank you", so you can't blame them for doing what grateful cats do.
I wish they'd keep to just lizards, you know...
