When it comes to animal symbolism, a major association of felines is with sex. Any feline-themed character is likely to be very sexually attractive and probably the most sexualised character in the work. This can range from actual Funny Animal cats, to characters who are to some degree feline-human hybrids or shifters, to alien or fantasy Cat Folk, to entirely human characters who have a cat theme. Because Most Writers Are Male, this usually applies to female characters, although there are male examples.
It's easy to see why: Cat ownership and feline traits have been historically associated with women (although in Real Life an equal number of men and women own cats). Many things men found attractive in women were projected onto cats. They are viewed as graceful, gymnastic and flexible; they have a mercurial temperament; if they aren't neutered they make it obvious to everyone around when they're in heat; and even when not in heat, they have no shame in their love of being petted and stroked. It can't be a coincidence that "sex kitten" rapidly became a term for female sex symbols.
Note that for this to be the case, the character's sexiness and feline associations must both be unusual within the work - if a work has a cast made up mostly of anthropomorphic cats, don't add the sexy one.

- The Trope Codifier in many ways is Catwoman, a morally ambiguous villain-turned-(anti)hero and arguably the Ms. Fanservice of the whole DC universe.
- Marvel has Catwoman's Alternate Company Equivalent Black Cat, and Tigra, a furry half-feline heroine in a bikini with definite animal instincts.
- On the male side, DC's villain Catman spent decades as something of a C-list joke... until Gail Simone got her hands on him in Secret Six and reinvented him as a badass, frequently shirtless, bisexual Anti-Villain.
- Downplayed with DC's Starfire. She's an alien whose species evolved from cat-like creatures and she's a beautiful, flirtatious, Innocent Fanservice Girl in a skimpy costume who became notorious by being one of the first heroic characters to have non-marital sex in a DC comic. However, there's relatively little feline about her appearance or personality, and the "evolved from cats" thing is rarely mentioned.

- The famous 1942 horror film Cat People expresses a major theme of fear of female sexuality in the story of a woman who (rightly or wrongly) believes that she will shift into a killer big cat if she becomes sexually active. It was remade in 1982 under the same title, and made much less ambiguous and much more graphically sexual.
- Discworld: When Nanny Ogg's cat Greedo is at times magically transformed into a human, he is described as a battle-scarred Hell-Bent for Leather tough guy exuding enough bad-boy sexuality to leave any non-lesbian woman who sees him practically catatonic.

They are also intensely masochistic, to the point of seeking out and enjoying their own Questionable Consent sexual murders.

- Catwoman in Batman is hot whether she's played by Julie Newmar, Lee Meriwether, or Eartha Kitt.
- The Cure's "The Love Cats" consists mostly of a whole string of feline metaphors for sex, including semi-orgasmic cat noises.
