Once the panic buyers get in and clear what remains on the shelves
there is going to be lot of hungry cats looking for more traditional
fare, so maybe not so good for the rats and mice

But they say it's only the posh pouches that in short supply, which are
probably eaten by the sort of cats that would turn their noses up at
eating actual wildlife :-P
