Cat like qualities in bed?

It could mean anything, depends on who said it. I assume you don't pee in bed and then scratch the blanket over the puddle. :)

Sounds like by the way you asked that question that you're pretty familiar with being in bed with a big variety of guys. Yeah, that'd mean you're wild in bed and are all over them after what you want. I wouldn't call that a good quality for a girl unless her main interest is making the bed scene and getting out of each one all she can get. It means you're overly aggressive in bed with a guy.

my dear they just mean that you are wild in bed. which in a guy world is actually good.

It means you don't just lay there, and are instead active and aggressive. Taste varies, but I think most guys prefer this.
