Cats do like beer - my last cat, Henry, and my current cat, Dave, both drunk it. Don't think I just poured it in the bowl and let them get hammered, 'cos I didn't. If you had a beer and put the glass on the floor, and a cat was about, inevitably there would be a cat/beer interface. We've recently had barbecues, and Dave will tip bottles over to get at the beer. He also eats prawn shells. Weirdo. We try and stop the beer drinking, as I think it' s probably not good for his little liver and kidneys. And it makes him a bit fighty, which, as he's already a bit minty, is not a lot of fun.
