Kitty also has a similarity to Black Cat from Spider-Man, because of her martial arts skills and black attire.
Kitty's very similar to Riley Daring from The Replacements because of her bossy, but kind-hearted personality. She is also the more responsible one but has to deal with Dudley the way Riley has to deal with Todd. They are also more trustworthy and have great athletic skills. They also both play the violin and are both voiced by Grey DeLisle.
Kitty also has remarkable similarities to Catwoman from the Batman franchise. Both wear black suits, both are skilled with martial arts, both use claws as weapons, both have green eyes, both are drawn to cat motifs, both have family issues (for Kitty, her shaky relationship with her mother and sister and for Catwoman, her abandonment by the hands of her father), both are arrogant, and both occasionally fight with the main character who wears black and has opposite methods in doing things right, but they help out anyway (Dudley and Batman, respectively). Grey DeLisle also voiced Catwoman in Batman: Arkham City which ironically, the way Kitty gets hung upside down and the method she uses to free herself in Doom and Gloom is similar to how Catwoman deals with her situation with Two-Face from the beginning of the game.
Grey DeLisle was also in the PBS children's TV show Danger Rangers, ironically enough voicing another character named Kitty who is also a cat.
In the Swedish dub, her name is Kitty Kattfot. Kattfot means Cat's foot.
She also can be compared to Carmelita Fox from Sly Cooper video game series. Both are law-enforcement officers, serious, sophisticated, and occasional fights with the main character who has opposite ways of doing things right. Grey DeLisle also voiced Carmelita in Sly Cooper: Thieves in Time. Ironically, when she first met Dudley, Kitty attempted to arrest him for hindering her investigation against Snaptrap is just like how Carmelita attempted to arrest Sly whenever she caught him stealing.
She is similar to Dana Scully from The X-Files because they are both hard working professional agents and they both have romantic feelings for their partners (Fox for Dana and Dudley for Kitty).
She is also similar to Sydney Drew from Power Rangers S.P.D. as they are both hardworking and they are both tough.
Kitty can also be compared to Lady Redundant Woman from the PBS Kids show WordGirl: Both wear gloves and boots, both have an ill temper, and both are voiced by Grey DeLisle.
Although Kitty is excellent in combat skills, she becomes completely helpless if her whiskers are cut, which causes her to lose her balance every time she stands up.
Although she can speak 120 different dialects, she only speaks English in every episode, but unlike Dudley, in the episode Dog Save the Queen, she seems not to have any problems in understanding the British accent.
According to her diary in Diary of a Mad Cat, there's a reason why she wears her gloves, but it was never (or hasn't been) revealed why she wears them

In Mall Rat, Kitty was referred to as a "mean lady".
In Booby Trap, Kitty had a signed poster of teen pop sensation Justin Timberwolf, a parody of Justin Timberlake. This could be another indication of her age, but then again there are adults that like Justin Timberlake. Kitty says that the poster is not hers, even if reacting nervously when it was destroyed by Bird Brain.
As a cat, it is shown throughout the episodes that she has an interest in sea food and, more specifically, fish.
It's revealed in Booby Trap that Kitty used to leave dead mice on the Chief's door step. This is an example of Kitty's feline nature.
It could be possible that Kitty has somewhat of a maternal side to her personality.
In the episode Puppy Love, it is shown that Kitty knows how to play a violin.
Kitty's face style always changes through the episodes (mostly, she has a round black nose other times she as a upside-down triangle black nose, also her eye style goes from cat shape eyes to cartoony eyes).
Kitty's long eyelashes might be a homage to Trixie Tang's eyelashes from Butch Hartman's other show The Fairly OddParents.
Kitty's fur color sometimes varies, from a light tan to a darker orange-tan shade.
When it comes to cat pleasures, Kitty becomes intoxicated (The Curse of King Mutt and Guard Dog), the noticeable effects being her eyes very wide open and swirly, her hair becoming messy, laughing insanely, her tongue poking open and drooling.

In Diary of a Mad Cat, when Dudley told her that he accidentally sent her diary to the entire city of Petropolis, her eyes turn red. This may have been a mistake while the episode was being made, but some say it could of showed her rage.
She was shown to be able to defuse a bomb in Happy Howl-O-Ween, but she didn't even know how to defuse the one in Kid Stuff. But since Happy Howl-O-Ween aired after Kid Stuff, she may have learned how to do it
