I suspect that may be the root of our problem, Ros.

One of my dogs is not cat friendly. And I mean seriously, unrepentantly Not. Cat. Friendly.

The dozen or so moggies who patrol the neighborhood have learned to steer clear of our garden; I suspect that the mice in the surrounding fields have now cottoned on to the fact that our garden has become a feline-free zone, and taken up asylum here.

Bit of a Teufelskreis.
