Yes it really has with us - much much colder - so I put on Seniorboy's electric blanket for the first time in many months.
The family are aghast but I'm listening to him snoring happily beneath his fleece and seeing his old bones lying deliciously long in his warm fug. (And he chose to go in there once his blanket was on.)
Does anyone else indulge their cat? And am I over-indulging him?
