Leaning on the Fourth Wall: Peanut does so here regarding a common fan reaction to the type of plot that was being lead into.
Super Speed Reading: Although it goes against the typical usage of the trope in that in this case it doesn't suggest super intelligence but rather just a lovable quirk.
Elements of Real Life Writes the Plot when Rick creates a one-off or arc of Spot (Superdog) based stories when he needs to be able to concentrate on something else in his life at the moment.
Unsettling Gender Reveal: Played straigh at first. Peanut thought Grape was male initially. After she talks to him about it and tries to assure him it won't change things between them and leaves him to go eat, Peanut holds his mouth in embarassment as he blushes.
Afraid Of Doctors: From the 23 January 2009 strip, Grape's first encounter with a veterinarian seemed like meeting Cthulhu. She still harbors a distrust of vets. Of note: animals in the Housepets! universe act much like furry children.
Everybody Was Kung-Fu Fighting: Channeled this as a kitten. Once she acquired a broom, The kidnapper and the alligator didn't know what they were getting into afterwards.
Fangirl: Lampshaded in Pridelands. She talks about the series in a straight and intelligent manner, but even she gets caught offguard from something as distracting as lions in tribal gear. She's also been caught writing fan fiction more than once.
Heroic Bystander/Badass Bystander: To both Max and Fox when they were young. Even more awesome when you notice she was younger and smaller than both of them!
Improbable Weapon User: Grape once threatened to stab Maxwell with a sharpened candy cane.
Killer Rabbit: Although Grape can have a short temper at times (especially when her naps are interrupted), she always approaches acts of violence with a straight face.
Like when she hit Bino over the head with a frying pan during one of his paranoid tirades.
Or when she ate the leader of some revolutionary Communist mice.
Or when she threatened King for flirting with Peanut's girlfriend, Tarot.
Or as a kitten she shredded both Puppy Bino's face as well as the sign saying "No Cats Allowed" without even changing expressions.
She's also threatened to "balance out" Maxwell's ears if he gets too fresh with her. If you've seen his ears, you can probably guess what that entails.
Nice Job Breaking It, Hero: Grape fears she may have pulled this herself after accusing the "author" of the Pridelands series of exploiting the work of her cat (the actual author of the series).She didn't.
Tom Boy: the comic was a good few months old before anyone realized Grape was female, much to her annoyance. The revelation didn't change her interactions with anyone except Peanut and Max. Lampshaded and punned here.
Tertiary Sexual Characteristics: As usual, there was confusion with her re-introduction. But in her first appearances she had the eyelashes Rick Griffin usually gives female characters in the strip. Then again, the fluorescent pink hearts helped.
Bino
Censor Bar: Bino uses one to cover his neck in "The Arc Specifically About Being Naked".
Catch Phrase: "Hi, I'm Daisy!" As of yet, it's the only thing she's ever said in the comic.
Living Prop: Pretty much. It gets turned Up to Eleven during the Wolfs' Christmas Party, when she's seenactually hanging from the ceiling with a bunch of party decorations.
Thicker Than Water: Despite how much of a jerk Bino is, he still hangs out with him and genuinely seems to enjoy it. This comes back to bite him, however, when King was shouting for Fido and Fox to stop Bino from breaking his watch. Fido stood outside the club within ears-length of the whole thing and was willing to let everything unfold, dismissing the event as petty. It took a threat from his girlfriend to stand up to Bino.
Half-Dressed Cartoon Animal: During his off-hours he is always seen wearing only a Rokushaku or Etchū fundoshi, a Japanese loin cloth. When at work he also wears a uniform and while at school he wears a shirt and tie tucked into the fundoshi.
Starving Student: Mr. Sandwich theorizes that Itsuki's invitation for the Sandwich family to eat at his apartment is a thinly-veiled attempt to let them know how much he needs a job.
Furry Fandom: Joey (a dog) likes to cosplay as a cat. He also draws well enough that he charged Peanut $10 for drawing a panel of Peanut's comic Spot (Superdog) in a much more detailed style than it's normally drawn.
Paper-Thin Disguise: Played straight at first with only Peanut and Grape finding out by being told, and then later averted when we're told that the cats all know he's a dog in a cat suit, and they're cool with it.
Kevin
Dumb Muscle: Anything that doesn't involve tackling is not likely to warrant his attention.
Used to Be a Sweet Kid: Joel had two dogs and a cat that he very much loved when he was a kid, but his parents were abusive towards them. Eventually they ran away and took him with them, but on the streets they quickly turned on him and ultimately abandoned him. Hence, his initial aversion to pets in general.
Lester
Ascended Extra: Was Ret Named with his own tag after beginning life under the tag "Joey's Creepy Friends".
Fan Dumb: In-universe, he's basically the poster boy for the trope.
Marvin
Expy: For Jon or Odie in the One-Off Garfield parodies.
Cheshire Cat Grin: He loves to do this whenever he's trying to drive a point home. Which is alot.
Ear Ache: The bite mark on his right ear. It's currently unknown how he received it.
Heroic Bystander: Was one back when him and Fox were kidnapped years back. While it was brave of him to try to distract Fluffy from Grape and Fox by jumping on him/her, it only ended up with the crocodile flattening him. Luckily, Grape saw what happened, and wrapped up where Max failed nicely afterwards.
High On Catnip: To the point of taking catnip from complete strangers.
Scare 'Em Straight: This is what happens to Max after a night in a haunted house. Compared to the other things being done to scare the others that night...
Unsettling Gender Reveal: Just like Peanut, it was played Straight as well at first. Maxwell knew Grape was one of the coolest cats in town. He suggested inviting Grape to the Yarn Ball to get to know some cats. When he suggests Grape to also get herself a girlfriend, she gets annoyed and tells him that she is a girl. Maxwell is so shocked that he has to ask if she's being serious. Not long after that though, he's then immediately asking to go out with her.
Miles & Lucretia
Everything's Worse with Wolves: Averted totally. Miles and Lucretia are your typical happily mated couple trying to fit in to suburban human society; he working for a group of Millionaire ferrets, she trying to remember that most Babylon Gardens residents prefer their food cooked before it is served.
Broken Pedestal: Played with and mostly subverted. While his owner does take credit for his work, Res wants it that way due to being very shy, and feeling indebted to her for taking him in when he was a stray.
One Of US: In-universe, he may or may not have been writing "saucy fan fiction" when Grape first met him.
Ascended Extra: Sabrina used to appear very rarely, now she appears a LOT more
Friend to All Living Things: She can't bring herself to kill the animals she manages to catch, so she tasks Fido with taking care of them instead. That's how Fido acquired his Head Pet, Spo.
She may be capable of (or has the connections to) have someone erased from existence. It's possible she was bluffing, but Fido took the threat very seriously.
Sasha
Abusive Parents: "Daddy" locks her out of the house pretty frequently, even in winter. The implications here are also grim when you think about it.
Bitch in Sheeps clothing: While no way NEAR as bad as most examples, it IS said on her character sheet that she dumps Bino on things like his position in with the other dogs....
Cloudcuckoolander: Sasha has this personality at times. Though, this page suggests some may be an act.
Genius Ditz: Either this, or she's practicing Obfuscating Stupidity, as she was able to compose a sonata in her head without ever sitting down at a piano, and knew all along that her boyfriend Bino was regifting her, after spending a good while acting like his presents were the best things ever.
Idiot Savant: If Sasha is as stupid as others say, she's this.
Stepford Smiler: Shades of type A with a heavy helping of denial. She comes off as an airhead most of the time, but is cheerful and friendly with all the other pets and mainly serves as comic relief. Then on Christmas Eve, we get this:
King: "Aren't you going to go home?" Sasha: "No, Daddy locked me out again 'cause I didn't get him any babes at the party. I think he just forgets when he's mad."
Spo:THIS IS EXCITING AND ALSO AWESOME Are you gonna go all Cops on him when you catch up? PLEASE TELL ME THERE WILL BE BLOOD Fido:THIS IS WHY I DON'T LET YOU TAG ALONG ON MY SHIFT
Instant Awesome, Just Add Dragons: Yep, she's the Spirit Dragon's avatar. However, the relationship between them is much more consensual than Pete and King's, and the only thing they've ever really disputed over is who should be Peanut's girlfriend.
Smart People Play Chess: Psychic chess, that is. And she wins, with "one eye tied behind her back", no less.
Strange Girl: She seems to bounce between being an extremely powerful psychic and someone who's just as willing to play pretend as the next pet. Or be both at once.
Terrance
Detective Animal: He is hired to act as liaison between the K-9 unit and forensics. He's decent, if a bit eccentric.
Tiger: Ha! I will never get tired of how you and the other dogs point out that my name is in fact that of a large cat, and that I hang out with a cat! Both: Hahahahahahaha! Tiger: I will kill you!!! I will kill your whole family!!!
