All's very well, thank you, Boaty, except for the fact that I can't go to bed because there's a cat on my knee (again!). He's the most nervous of the four and can never seem to find somewhere to curl up where he feels really safe and happy. So now that, for the first time in months, he's got himself really settled on my knee, I haven't got the heart to move him.
As an aside, the wee white tornado doesn't live here, I only look after the lunatic when mum and dad are away. They say she's my dog really, they only look after her most of the time.
