"Can use use a vacuum cleaner to clean a cat?" ... Yes, but I've found that the cat might not like it. I'd also recommend using the upholstery tool and whatever you do, don't allow the cats tail (or any other part) to come into contact with the rotating brushes. For a moderately dirty cat, the vacuum's suction should be enough. If you have a really dirty cat, or a lot of cats to clean at once, try an automatic car wash instead (just make sure it's the kind where the doors close before the wash starts, otherwise too many escape).
