There's no such thing as 'a bit hot' for us Jon - any kind of hot is just fine. We keep our sitting room at 27C all day and evening. It only goes off when we get under our 15 tog goose down duvet. I suppose our Siamese cats enjoy living here, as it's always sweltering. When our neighbour comes round for a cuppa, she gets redder and redder in the face (they have no central heating at all, just a wood burner)

Aren't cats funny with their rituals? Our SmokeyPokey loves to have his bottom gently smacked, it helps his stiff joints. Every morning at 6am I'm stood there in my dressing gown smacking his rear end for ages while gasping for a cup of tea.
Murphy has a secret hideaway behind the TV (I've put a little bed there right up against a radiator) and he shoots out of the kitchen when I get up and makes for his hideyhole.
At bedtime, I only have to clap my hands a couple of times and they trot obediently off to the kitchen to bed.
