Yes Pasta, that's the cat! though 'mine' was a bit fluffier around the face, and had very pointy tufts at the top of its ears, making them pointy, correction: more pointy.
It would be truly spooky if you, Magpie and I were all being visited by a very similar cat, so I'm glad to say that 'mine' was a lovely light silvery grey with very very white fluffy undersides and tail.
And yes, they are big units, aren't they? This one isn't as huge as some of the ones on the internet, it's just a very large cat rather than a medium-sized-dog-sized cat,
It has been around before, I just didn't get such a good look at it then, so I think it is allowed out. The idea of such a big beast being an indoor cat is odd...
I'll see if I have a photo from the previous visit, and I hope it comes back and does its 'lion couchant' post again so I can get a photo that does it justice.
Anything practical we can do to be of assistance, Myrtle?
