* In "That's My Mommy," Quacker confuses Tom as his mother, despite Tom's efforts to eat him. When Quacker [[OhCrap realizes this]] (while preparing a recipe for "Mommy"), he looks forlorn and marches up a spoon leaning on the pot, preparing to cook himself ("Well, if my nice sweet mommy wants a duck dinner, my nice sweet mommy's gonna ''have'' a duck dinner!"). To really [[TearJerker jerk the tears]], Quacker says, "[[PlatonicDeclarationOfLove I still love you, Mommy!]]" just before he jumps into the water. It is at this point that Tom has a change of heart and saves Quacker from a boiling death. The two hug as [[OcularGushers tears stream down Tom's cheeks]] and Quacker says, "My nice mommy. My nice, nice mommy!" And the cartoon ends with the two quacking at each other in a duck pond.
--> '''Quacker:''' (proudly) [[TitleDrop That's my mommy!]]
** Made even more heartwarming by Tom, [[OOCIsSeriousBusiness one-half of the greatest silent duo in history]], giving out a BigNo before he saves Quacker.
** Tom really starts having a change of heart when Quacker tells Tom to take a break and let him cook. And it's solidified when Quacker tells him that he still loves him.
* The endings of "The Night Before Christmas" and "Snowbody Loves Me" are essentially the same thing – Tom makes Jerry stay out in the cold, but [[MyGodWhatHaveIDone later has a change of heart]] and rescues him from freezing to death.
** "Snowbody Loves Me" is especially sweet as the cartoon ends with Tom playing the piano for Jerry to dance to.
* In "WesternAnimation/PuppyTale", Tom kicks Jerry and a puppy Jerry had taken in out the house. During the night, a severe thunderstorm kicks up and Tom feels guilty for what he did, worrying that Jerry and the puppy could drown in the flood. He goes out to find them, only to be swept away by the flood waters. Jerry and the puppy (who were safe), find him and bring him back to care for him. When Tom wakes up, he then gives the puppy milk and the puppy calls all his friends to share with them. Tom and Jerry just look on happily as the credits roll.
* At the end of "Just Ducky," Jerry and Quacker save Tom from drowning. Later on, when Tom comes down with a bad cold, Jerry wraps him in a blanket and feeds him soup, and the two wave to the ducks as they pass by.
** Until the rescue, Quacker couldn't swim. Tom crying for help as he was about to drown is what finally helped him learn how because there was no one else there to save Tom.
* In "Hatch Up Your Troubles" and its remake "The Egg and Jerry", a woodpecker hatches and believes Jerry is its mother (because its egg rolled into Jerry's home). The bird irritates Jerry and he eventually kicks it out, but when Tom goes after it, Jerry saves it multiple times. Then, when its real mother comes to get it, it flies away with her, leaving Jerry sad until the woodpecker returns to give Jerry a kiss and Jerry then happily waves goodbye. Aww.
* After the [[NightmareFuel disturbingly]] [[TearJerker depressing]] events in "Heavenly Puss", it is to the relief of many watchers that it was AllJustADream and Tom hugs and kisses a bewildered Jerry (which is also funny at the same time).
** Even before that, Jerry signs the Certificate of Forgiveness when he realizes [[DraggedOffToHell what will happen to Tom]] if it isn't signed.
** The above example needs to be elaborated on. Some on this very site have noted how [[FridgeHorror unnerving]] it is that Tom thinks his chase with Jerry is gonna land him in Hell. And yet when this dream version of Jerry sees what awaits his enemy if he doesn't get his certificate signed, what does he do? Sign instantly, indicating that, even while they're fighting each other, Tom sees some good in his foe, and based on Jerry just accepting Tom hugging him at the end, it seems to be mutual.
* In the Creator/ChuckJones cartoon "The A-Tom-Inable Snowman," when Tom catches a cold and is shivering/sneezing like mad, (or at least, pretending to,) Jerry sits close by, looking ''incredibly'' worried about the guy. Jerry even begins to hand him a tissue when he weakly gestures towards the tissue box; (that is, until Tom quickly recovers and grabs Jerry, preparing to eat him…)
** In an odd example of an entire character being a Crowning Moment of Heartwarming, there's the Saint Bernard who repeatedly pops in and out of the cartoon to rescue Tom. Doesn't hurt that the dog's character design is irresistibly cute and dopey-looking.
* "WesternAnimation/BlueCatBlues", [[TearJerker of all episodes]], actually has quite a few moments:
** First, there's the general behavior of Tom and Jerry through the episode: not only do they begin as friends (something odd in and of itself), but it's also, perhaps, the one episode where Jerry doesn't try to hurt Tom and Tom only hurts Jerry in a non-malicious, not-fully-intentional way, since he's either [[LackOfEmpathy too focused on his girlfriend, unattentive or drunk]].
** At the very beginning of the flashback we see Tom and Jerry sharing a drink and, when Tom accidentally sucks Jerry in with his straw, he gets him out, cleans him up and, when Jerry seems annoyed, he apologetically holds him up so he can drink the rest of the lemonade. This may be the nicest Tom has ever been to him, or at least, one of his nicer moments; and he didn't even need to be guilt-tripped or forced into it.
** Jerry's [[{{Determinator}} constant attempts at trying to bring Tom back to his senses]], even if unsuccessful, prove how much he cared about him. He tried to drag Tom away from the girl, stop him on his tracks by grabbing his legs [[AintTooProudToBeg and even begged him on his knees to come back]] while Tom was DrowningHisSorrows because [[HeroicBSOD of him failing to impress the gal of his dreams]].
*** Related to the above, Jerry rescuing Tom from literally going down the drain and drowning. Even if Tom had thus far stepped on him, shaken him over and pushed him away in more ways than one, Jerry couldn't let his old friend die like that.
** In the end, a particularly macabre and somber example still occurs: when Jerry has his heart broken by HIS girlfriend, he goes with Tom to also let the train run him over and a depressed Tom, implicitly realizing ''why'' Jerry is there, steps aside and leaves him a spot to sit on. Despite how depressing it all is, how much he's lost and how self-absorbed (or girlfriend-absorbed) he was through most of the episode, Tom had one final moment of kindness by allowing his old friend by his side when he was suffering the same way he was so they can [[TogetherInDeath end their suffering together]].
* Then there's "The Cat and the Mermouse", where Jerry saves Tom from drowning. Right after coming to, Tom looks at Jerry with sincere gratitude and gingerly shakes his hand.
* The ending of "Little School Mouse" is both hilarious and heartwarming – all through the cartoon, Jerry has been acting as a teacher to Nibbles (complete with blackboard and pointer) teaching and testing him in the ways of cat-outwitting. Nibbles has managed to pull off most of the tests, though generally (and to Jerry's increasing frustration) through kindly asking Tom to comply. The final test is to tie a bell around the cat's neck, which Nibbles solves by gift-wrapping the bell and giving it to Tom as a present. Tom ''loves'' the present, puts it around his neck and is thrilled with Nibbles's kindness. The final scene has Nibbles as the teacher, now teaching a grumpy Jerry and a smiling, enthusiastic Tom that cats and mice should be friends.
* "Mouse In Manhattan". Jerry ditches Tom because he's bored of country life and heads to UsefulNotes/NewYorkCity. The end of the episode has Jerry ''running back'' to the relative safety of his old home, and kissing a ''confused'' Tom (who never read the goodbye note Jerry left).
* The episode "The Truce Hurts" has Tom, Jerry, and Spike putting aside their differences to live together happily. [[StatusQuoIsGod Even if it's short-lived,]] they actually try to make the effort to protect each other, as Tom saves Jerry from becoming Butch's lunch, and Spike punches out a dog ready to eat Tom. It's actually pretty sweet seeing them get along, proving that, when motivated, they actually would be able to live together in harmony.
** Then, the ClipShow episode "Matinee Mouse" has a different ending for them. In an InUniverse BreakingTheFourthWall, the trio stop their fighting to watch the Chuck Jones version of Tom and Jerry fighting.
* "Neapolitan Mouse". Aside from a quick chase in the beginning, there are no chases, no plots, no elaborate schemes, nothing like that. It's just Tom and Jerry befriending a little Italian mouse, who is a huge fan of their cartoons, and enjoying the sights, smells and delicacies Italy has to offer. Tupo may have only appeared in that one episode, but he is very memorable for a very big reason.
** The most heartwarming part of this short is arguably how Tupo defends first Jerry from Tom, and later Tom from a local bullying greyhound, with the reasoning that he ''hates'' it when someone thinks they can bully others just because they are bigger and stronger. Tupo possesses a degree of super strength and uses it to protect anyone who is victimized.
* In "The Million Dollar Cat", Tom is able to inherit a million dollars on one condition: he doesn't hurt any other being. After an episode's worth of [[JerkassBall torture from Jerry]] abusing this handicap, Tom finally cracks and attacks Jerry. Though he initially [[SuddenlySpeaking laments "throwing away a million dollars"]], he happily goes back to attacking Jerry, not caring because his moral victory is worth more to him than the money.
* At the end of both "Lonesome Mouse," and "Old Rocking Chair Tom," after Tom "rescues" Mammy Two-Shoes from Jerry (who in both cases were really just plotting to let Tom back into the house), Mammy rewards him by giving him a pie, and apologizes for throwing him out of the house. Harsh as she can often be, it's pretty clear that she values Tom greatly.
** In the latter example, Tom shares his pie with Jerry.
* "Life With Tom" is a ClipShow featuring previous Tom and Jerry cartoons written as the titular book. Tom is furious that the book has made him a laughingstock… but then Jerry revealed that he instructed the publishers of his novel to give half of his ''$50,000 royalties'' to Tom. When adjusted for inflation, that's ''$489,853.93'' in 2021.
** Simultaneously funny and heartwarming is how Tom then flips through the book again and finds it ActuallyPrettyFunny, with Jerry sincerely smiling.
* In "Professor Tom", Jerry befriends a young kitten named Topsy whom Tom was trying to instruct in the ways of cats catching mice. Jerry teaches Topsy that cat and mice like them should be friends instead of enemies and Topsy, almost from the start, shows lots of admiration towards Jerry's lessons (while he was bored with Tom's about cats and mice being enemies). Through the episode, Jerry and Topsy work together, help each other (of particular mention is the fact that Jerry [[PapaWolf saved Topsy from]] [[CorporalPunishment getting spanked by Tom]] and after they defeat him, the two walk away as friends, holding hands. Topsy even has the detail of dusting off Tom's teacher hat and giving it to Jerry as an admission of him as his new teacher.
* Jerry saving a frozen Tom in "Buddies Thicker Than Water" after Tom writes him a note to help him. Jerry brings him in the house, thaws him out and serves him a delicious meal. They spend some nice time together while drinking champagne. That is, until Tom's owner returns and as she was ready to throw him out again, he convinces her to remain by catching Jerry and throwing him outside.
* "Johann Mouse": At first, Tom learns the piano to catch Jerry, since Jerry can't resist the allure of the waltz. Then the servants see their interactions and word goes to the king, who asks for the duo to perform for them. Cue Tom and Jerry dressed to the nines and performing with sincerity. While Tom still wants to catch Jerry, it feels like more of an established relationship.
* In "Jerry And The Lion", Jerry helps an escaped circus lion (who sounds quite a bit like Bert Lahr – no doubt a deliberate ShoutOut to Film/TheWizardOfOz since this is an MGM cartoon, after all) find his way to a ship bound to Africa. The poor lion had begged for help because he couldn't stand one more day of captivity in the circus. After an entire cartoon of evading Tom's efforts to catch the lion and land a reward for it, they end up at the docks where Jerry helps him sneak into the ship's lifeboat. The lion tearfully calls back, "Goodbye, pal… and thanks." As the ship sails into the distance, Jerry waves goodbye with his hankie… which he briefly uses to wipe away a few tears of his own, before smiling and waving again, sad to see his friend go, but glad to have helped him.
* "I'm Just Wild About Jerry": After all the times that Tom's been hit by a train twice and then chasing Jerry through the toy store before getting ejected back onto the train tracks, it appears that Tom's about to get hit by a third train… until Jerry switches the tracks to save his old foe. Because of his selfless act of bravery and kindness, Jerry gets an AngelicTransformation as he is sprouting wings and a halo before [[AscendToAHigherPlaneOfExistence flying off to the moonlight in the heavens above]]. Even Tom takes a look at his now-angelic rival upon his departure and waves goodbye to him as the episode ends on a sweet note.
* "WesternAnimation/TheLittleOrphan": On Thanksgiving, Jerry is given a very hungry Nibbles (here, "the little orphan" of the title) to sponsor as a guest for the holidays. Though at times annoyed by Nibbles just running recklessly into danger for food, Jerry nonetheless looks out for him and endeavors to give him a joyful, food-filled Thanksgiving, while also beating up Tom when the latter threatens to eat Nibbles. This protectiveness isn't unreciprocated, as Nibbles, upon seeing Tom capture Jerry, flings a pie, a lit candle (lighting Tom on fire), and finally a bottle onto Tom to save Jerry, sending him crashing into the cupboard.
** At the end of the episode, the three of them, having reached a truce, gather around the dinner table in peace and saying grace, before happily getting ready to dig into the turkey. [[MoodWhiplash Unfortunately for Tom AND Jerry, Nibbles finishes the whole bird in seconds down to the bones]].
