@ossobuco,
Interesting night.
Sebastian had some sort of episode and ran into my head with stunning force.
Then he leaped up onto a curtain rail.
Viola, later, decided she wanted to do curtain rails too. Did one of her lengthy, intense concentration attempts. Couldn't quite make herself do the last step of getting her back legs up there, which I was quite pleased about, as it would have been a long fall.
She's such a funny little thing.....doesn't have Sebastian's athleticism, sadly....or perhaps it's just as well!
