Well, I've got a defective tabby wee furry git and a small ginger sheep that's very pretty, but thick as a barn door.
They're both utter knobs in their own way. As the fancy picnic hamper (£2 in a charity shop c.2002) that is used as an observation post/manicure bar (when the fluffy one isn't dispensing summary justice from the kitchen chair and therefore protecting the table leg from looking like a beaver has got to it) can testify. Particularly when I vacuum up the shredded bits every time I do the upstairs.
Remember - ACAB. All Cats Are Bastards.
Some are just better at hiding their sociopathy when it's the person who opens the tins.
