On three occasions now, my cat has either bitten me or tried to bite me when I have gotten drunk.
The way it happens is I'll be doing literally nothing, sitting there thinking or reading a book, while drunk. The cat will then suddenly yowl/cry and bite me, but one of those controlled bites that doesn't break the skin, but is more forceful than a play bite.
What the fuck is going on? I assume it is related to the alcohol, of course, something about it is upsetting to the cat. Does it sense that I act differently and that upsets it? Is the odor offensive to it?
Cat never does this any other time.
