* [[http://www.kevinandkell.com/2001/kk1026.html This]] strip reminds us that scrolling (as in webpages) was named after the paper scroll.
* When she first encounters a homosexual couple in Domain, formerly human Danielle is surprised by how accepted it is, as where she comes from (our earth), people make a big deal about dating the same sex. She assumes it's because there's just not enough room for another form of prejudice on top of all the other rampant prejudices that the world experiences via it's literal dog eat dog nature... But it's far more likely this is a hold over from evolution. There are over 1000 species that demonstrate homosexual behaviour, from male penguins raising eggs together, to giraffes partnering with the same gender. Humans are the only ones who have a problem with it. So a world dominated by different animals instead of humans just ''wouldn't care''.
* Rudy’s extremely intolerant reaction to Bruno becoming an herbivore comes off as out of the blue and even [[OutOfCharacter out of character]] for the normally loyal canine. However, consider this: Rudy was raised in predator society for most of his life, spending all his time with carnivores and barely giving prey species a second thought except as dinner—in other words, he saw prey (and thus herbivores) as inferiors, or at least a class that belonged in a separate society away from him. Then, over the course of a year and a half, his mother marries a rabbit, he’s forced to live with a new rabbit stepfather and porcupine stepsister, he discovers his biological father [[spoiler: had cheated on his mother]], then that his biggest enemy is [[spoiler: his half-brother]], and finally learns that his best friend has been in a socially-unacceptable interspecies relationship with a sheep for several years without telling him. Any one of those would be a tough pill to swallow, and he was hit by all of them within just months of each other. When you remember that Rudy and Bruno have been friends since infanthood, Rudy’s behavior suddenly makes sense: Throughout all his trials, Bruno has been the one constant that Rudy could trust in, being his closest carnivorous friend when it seems like herbivores are taking over his life. When even ''Bruno'' seems to betray him, it’s the last straw. No wonder Rudy panics.
* ''Of course'' Ophelia [[https://kevinandkell.com/2020/kk0611.html was hungry for gopher]] after she was initially rescued by George. Wearing a [[UsefulNotes/COVID19Pandemic facemask]] while underground, she was constantly rebreathing George's scent while [[https://kevinandkell.com/2020/kk0604.html originally under the impression that he was a weasel]] like her.

!!FridgeHorror

* The fact that hunting, killing, and eating other sentient beings is ''routine'' in this world is regarded as ordinary and acceptable. Starting in 2010, Kell herself runs a company dedicated to doing this as efficiently and widely as possible. On its face, this ''should'' be a horror worse than the Holocaust. The strip plays all of this for light comedy.
* Not to mention that it's perfectly acceptable for a CEO to be eaten alive by anyone who wants to succeed the position. And it is in fact the ''normal'' way of doing things, to the extent that letting a defeated foe ''live'' is unheard of. Furthermore, older strips joke about workers being "fired" actually being killed and Kell is unusual for getting let go without being devoured.
* It makes sense that Corrie Dale (under her reversed name, and as a wolf, as she was using Ralph's pelt as a disguise at the time) [[https://kevinandkell.com/2000/kk0807.html would be dismayed at suddenly being placed on the Species Registry.]] Technically, she was a runaway from a research facility, which adopted her under false pretenses as a lamb, and used her for cloning experiments. She likely feared that the research facility would put two and two together, and find her relatively easy. ([[https://kevinandkell.com/2001/kk0925.html Something that did later come to pass...though, due to bad eyesight, they kidnapped Bruno instead.]])
* With the inclusion of athletics and especially the Olympics in recent comics, the continued references to predation seem to imply that the losers of an event could end up ''eaten''. Very jarring when applied to how human athletes are treated, especially in one instance where it looks like they actually off the ''winners.'' That just gets confusing.
* Francis is biologically human. Which means he won't be able to produce offspring with his future partner.
** Who knows in their universe? We've seen at least one reptile/mammal cross produce viable offspring (tortoise Sheldon Dome and his weasel campaign manager), so it wouldn't be a huge surprise for Francis (a primate) to be able to cross-breed with a mammal, at least.
* When walking in the Rabbit Warren one day, Kevin and Rudy (who had just moved there with Fiona) [[https://kevinandkell.com/2024/kk0405.html happened upon a rabbit whose ears were cropped down really short]] where they had obviously been cut off by some sort of blade. Kevin immediately warned Rudy not to open a trap door to the surface without an all-clear, because of the possibility of lawn mowers. Although such a wound would not be automatically fatal (see: Creator/VincentVanGogh), one can only imagine just how horrific such an injury would be. Both with all the blood (which would still be a lot even if not life-threatening), but also with how close the blades would actually be to their head. And imagine [[OffWithHisHead if they went up higher into the lawn mower's business end without realizing it was there]].

!!FridgeLogic
* When TheReveal came that [[https://kevinandkell.com/2002/kk0519.html Vin Vulpen was Rudy's brother]] via infidelity on the part of his father, Randy Foxglove, it was noted that [[https://kevinandkell.com/2002/kk0520.html Kell had suspected this from Randy]] but never had the evidence to back it up. It clearly happened before Randy and Kell decided to start their family, since Vin is established to be Lindesfarne's age. This raises a few questions. It's possible that Randy cheated before he and Kell married, as an early presumption was that Kell had Rudy at a relatively young age, and Randy died when Rudy was a toddler.
** It could explain why Kell went a few years into her and Randy's marriage before deciding to have children with him.
** It could also explain why she had Rudy's last name changed back to Dewclaw after Randy died [[AmbiguousSituation presuming it was ever Foxglove in the first place]]--[[ProfessionalMaidenName much less if she ever took his last name]].
* One recurring background couple is a male donkey and a female elephant who are in a relationship - they attend the same interspecies relationship group that the title characters attend, and they're later shown at the same interspecies birthing class that George and Danielle attend. However, if you move beyond the obvious joke about American politics, it shouldn't be that controversial of a couple - donkeys and elephants are both herbivores. They're much closer in terms of diet than, for example, Rudy and Fiona are.
** It's possible that beyond the joke, they both realize that their support of the more controversial couples will boost morale. Or that they're from families that are extremely strict about dating outside your species.
* One wonders how Kell and Sheila can routinely pull off switching places, since both are wolves and one is involved with a lion. Predators tend to have quite good senses of smell, so how do cousins (who are not, so far as we've been told, the offspring of any identical twins) manage to even ''smell'' identical enough to fool Kell's mother, Sheila's partner, etc.?
** It's been established that Sheila is a bit of a [[GirlyGirl Girly Girl]] who wears make-up and trendy clothes. It's not a stretch to assume that she wears perfume, and that Kell could wear the perfume and Sheila could wash it off to cement the ruse.
*** That might raise the question of how the lions and canines can't still smell the traces of perfume on Sheila, but it might be a case of the family not looking (or in this case, smelling) too closely because if it's obvious who's in front of them, why bother taking a second look to make sure?
*** On Lindesfarne's [[AllThereInTheManual Tumblr blog]] she revealed Kell and Sheila don't just look identical with no makeup on, by some quirk of their genetics, they have identical ''scents''. Since most of the K&K world sees everyone else through their nose, they aren't able to tell the difference, and even those that rely on eyesight like Francis or an eagle wouldn't be able to tell either due to their identical physical appearances.
