Ok cat killed 4 mice last night, and left them on the kitchen floor
3 of the corpses were near the cat flap, so it's perfectly feasible that she brought them in from outside.
There are no mouse droppings in the house,I had a paranoid check.
These mice were about 3" long and had SHORT tails- all the pictures of both house and field mice I have found show long tails, so what were they?
Voles? Do voles have a short tail?
She is an old cat- at least 15, and I suspect she found a nest...we've had them one at a time before, but never 4!
Don't need any mose destruction advice- we have a cat! But would be interested to know whether Simba is singlehandedly causing the extinction of a rare species!!
