I foolishly went outside but when I returned, my cat flap had frozen. It was minus 7C.
I used my initiative and tapped on Jack and Stella’s bedroom window (luckily we
live in bungalow) and they let me in.
How can I stop my cat flap freezing up again?

Bird food is not all that expensive so I boost bird numbers above natural levels. The excess feeds the cats far more cheaply than Kit-e-Kat, Whiskas, etc.

Note the daytime frost - that just about keeps me 'on-topic'
