Something’s up

Ooooo – there is definitely something funny going on in Baskerville Manor. 
Yours Truly Confused had some visitors yesterday evening. They came in with two crate things. There was a really, really interesting scent, but before I could investigate properly, I was ushered out into the back garden. I was let in after the visitors had gone and YTC spent the evening going up and down into the attic.
I can hear her speaking to somebody called Mr Kit-Kat and somebody called Little Jet-Black, but I can’t hear anybody replying to her.  I’m a bit concerned about her sanity. 
Whenever she comes downstairs from the attic, that really, really interesting scent is on her, but she’s not telling me anything.
This morning the man from Tesco brought the groceries and among them was this stuff called “litter”.  Why on earth would she want to buy litter?  The Diva, The Big Guy and I can provide oodles of it for free anytime she likes, just let us at the bin.
Must investigate.
