History Heartwarming / CatDog

* ''[=CatDog=]: The Great Parent Mystery'' is full of these, but this one reveals Cat's true character beyond the shadow of a doubt. After hitting another dead-end in their search, the ever cynical Cat shouts they are going home... only to be horrified when Dog agrees with him. The broken Dog gives up, ripping up his book of theories and admitting he wishes he gave up easier like his brother. Cat tells him not to say that, admitting he wishes he were more like Dog, with boundless determination. They then make a vow to find their parents no matter what and reassures him by telling him that they will always have each other. "We are brothers." Giving that Cat and Dog are usually PolarOppositeTwins, the scene of brotherly love is very powerful.

* ''[[MusicalEpisode It’s a Wonderful Half Life]]'', full stop. The crowning moment definitely being when dream!Dog rescues dream!Cat from the Greasers and they run alongside a train to escape. Dog jumps onboard and stretches his arm out for Cat. It’s when they finally reach each other’s hands that their individual dreams merge into one.

* Lola and [=CatDog=] apologizing to each other and becoming friends at the end of "Sweet and Lola".

* "Work Force": In this episode, [=CatDog=], Mervis and Dunglap get jobs licking cereal boxes at a factory. Dog gets a promotion and the power goes to his head. He fires Dunglap, and then fires Cat for no good reason. Cat gets angry at this display of injustice and encourages all the other workers to go on strike. Dog tries to lick all the boxes by himself and fails, and Cat starts laughing, with everyone else joining in. Once Cat notices everyone else laughing, his BigBrotherInstinct kicks in and he stops laughing and tries to help Dog.

[[caption-width-right:300:" [[TrueCompanions It just doesn’t get any better than this.]]"]]

* In ''A Very CatDog Christmas'', [[spoiler: Cat calls his usually unwanted guests (the Greasers, Eddie the Squirrel, Winslow, Rancid Rabbit, and Rancie) like family. They all have a group hug for once, not hating each other like in every other episode.]]

* The beginning of ''Climb Every CatDog'' is one of the very rare times [[NiceGuy Dog]] flies into a growling rage and tries to attack the antagonist of the episode. Why? [[BigBrotherInstinct Because she called Cat a loser]].

** When it seems like [=CatDog=] and [[spoiler: their adoptive parents]] are screwed by Winslow, The Greasers, and a slew of other individuals for the sake of {{Jerkass}}itude, the Tornado that separated the two from [[spoiler: their adoptive parents]] comes in, and ''by sheer luck'', it throws the formers away to Nearburg and the latters get eaten by the lake monster. Considering '''[[SadistShow everything]]''' [=CatDog=] go through, it is ''satisifying'' seeing all the asses who give them hell finally get LaserGuidedKarma and [=CatDog=] '''finally''' [[EarnYourHappyEnding get the happy ending they derserve]].

--->[[spoiler:'''Dad:''' (''paraphrased'') Heck, we don't know where [[CartoonCreature your mother]] came from either, but that doesn’t matter because she's your mother, and you're our boys.]]

--->[[spoiler:'''Dad:''' (''paraphrased'') Well, we don't know where [[CartoonCreature your mother]] came from either, but we don't care because she's your mom and you're our boys.]]

-->[=CatDog=], [=CatDog=] [[spoiler: alone no more is the little [=CatDog=]]].

-->'''Giant Monster''': [[spoiler:HI HO DIGGETY!]]

-->[[spoiler:'''Dad:''' (''paraphrased'') Well, we don't know where [[CartoonCreature your mother]] came from either, but we don't care because she's your mom and you're our boys.]]

-->[[spoiler:'''Mom:''' (''gasps and pulls out the half of the binky that was left behind after [=CatDog=] was separated from them'') You kept it!]]

* A minor one at the end of "Flea or Die"; the fleas end up so out of control that even the fleabelt can't stop them. This leads Cat to realize that their only chance is the flea bath Rancid had offered them earlier. When they get to the hospital Rancid is [[EvenEvilHasStandards visibly horrified]] at how out of control the fleas have gotten and [[PetTheDog gives them the flea bath with no (apparent) ulterior motive]]. Hey, coming from [[BigBad Rancid]], that kind of thing is huge.

* In “You’re Fired”, another one of Cat’s attempts to impress Talullah fails. Dog attempts to console Cat by telling him “You still have me”.

* Really, any time Cat sticks up for his brother is this, showing that he still cares for Dog despite all the stuff he does to him. For example, in "[=CatDog=] 3001," Cat and Dog have been separated from each other because [[ItMakesSenseInContext the people of the future think Dog was a hero and want him to save them from a giant descendant of Winslow]]. Winslow's descendant defeats Dog, but Cat sees what happened to his brother and - in what is also an AwesomeMoment - puts him and Dog back together and beats the bad guy by [[ItMakesSenseInContext using Dog as a vacuum to suck him into their body.]]

Dog jumps onboard and stretches his arm out for Cat. It’s when they finally reach each other’s hands that their individual dreams merge into one.

* In a way, the ending of "Picture This". Dog is ashamed to find everyone in Nearburg angry about the pictures he took of them, but when his work is praised by an art critic, everyone forgives Dog and they encourage him to continue photographing them in embarrassing situations.
