it's a thing, isn't it?
All calm till sometime between nine & half ten & then rampaging up & down the stairs, creeping up & goosing each other, squawking & clouting each other round the chops.
Very entertaining, but I could do without the mad leaps onto furniture & clawing at the curtains.
My cats are nearly 9 FFS - I thought they might have calmed down a bit by now
