As so far as Cartier's fragrance is concerned - I'm unfamiliar with it but Fragrantica lists it as unisex.
For your other question, there are a couple of fragrances that are classified as feminine but I would NOT consider them to be.
Sycomore is supposedly a women's scent, but it sure smells masculine (and incredible) to my nose. The fact that it's marketed as a women's frag won't stop me wearing it.
A lot of people here will tell you that if you like a fragrance (and it doesn't smell entirely too feminine) that you should just wear it. Lots of guys here rave about the original Jicky, and that's supposedly a women's frag too.
The problem with Arsenal is that they always try to walk it in!
