Mc moves to Devildom permanently, as does their cats
How the relationship between your cats and the brothers work
2395 words | gn reader
When Diavolo gave you the offer to permanently move to Devildom, you readily accepted. On one condition.
Your cats. You lovely, darling cats you had in the over world. The cats you cried over abandoning until Barbatos comforted you, explaining the little creatures were to be well taken care of during your stay.
But moving long term means you need your babies. Even if Lucifer looked less than pleased at your conditions.
Lucky for you, Barbatos quickly arranged for your cats to be brought to their new forever home.
Now the house is stocked with cat food, toys and treats for the tiny orange tabby, butter, and the large long haired Siberian ragdoll, Tofu.
But… How well do they get along with everyone?
Lucifer
Lucifer had a hard rule: no pets.
Which is notably hypocritically, considering cerberus. Also considering Mammons gaggle of crows he communed with could definitely be considered pets… and henry…
Okay, Lucifer told the younger siblings no pets while repeatedly breaking the rules for his and the older brothers' benefit.
Alas, then came Butter and Tofu.
Safe to say, the first two months were spent diligently avoiding the two fluffy kitties.
Picking cat hair off his clothes with a disgusted face, using a spray bottle to stop them from scratching the furniture and ignoring when butter screamed his head off in an attempt to have some of Lucifer's food.
However, Tofu is quite the charmer.
A large yet tiny and delicate fluffy ball of love. A little shy but needy for affection. A sly bastard who can open doors.
Specifically Lucifer's bedroom door. So she can lay on his pillows and stare unblinking, unmoving, and desperately adorable.
With a soft knock you open Lucifer's study, it's late and a Friday, yet you haven't seen tofu for hours.
“Sorry, but have you seen Tofu she didn’t come down for dinner and-” you stop dead in your tracks, looking at the opposing embodiment of pride frozen in a plush red chair.
With a glass of demonus in one hand, and the other mid stroke along the purring cats back.
“Oh-” You giggle a little, composing yourself, “Sorry, if you could show her where her food is later that’d be great. I’ll leave you too alone.” You begin to leave, closing the office door.
“Wait!” Lucifer almost gets up, but tofu gently kneads his leg, causing him to stay put, “This isn’t-” You don’t hear him as the door clicks shut.
Smiling to yourself, you take a moment before speed walking to the planetarium to tell Belphie what you just saw.
Mammon
Listen, mammon is overjoyed you are moving in permanently.
Obviously he won't ever tell you that. But the idea of you moving back to the human world where you will age and die and he will never see you again makes him genuinely sob into his pillow at least once a week.
Just… cats? Really?
They are mean and shed everywhere and butter is notorious for breaking into his room and sleeping on the hood of his car.
Genuinely, multiple times a week he’s shooing the little guy out of his room.
And, he gets it, really. From a distance they are cute. But that's not his vibe. Until one night of course.
It's dark, even for Devildom. The Mammons room is no different, room pitch black as he lays in bed.
Shirtless and sweating for all the wrong reasons as he clutches a pillow tight to his chest. Lately… his nightmares have gotten worse. He awoke screaming, thrashing and already crying numerous times this month.
This is one of those times.
Where he's sobbing into a pillow, wings tucked close to his body as he cries over a dream he doesn’t even remember but it doesn’t stop the never ending tears.
He's so distracted he doesn’t hear the little orange menace use his little paws to pull Mammon's door open. Only when a small pressure is placed on the bed does Mammon sit up, eyes blood shot.
“Come on…” he mutters weakly, swatting at butter. Alas, butter merely dodges and walks closer, placing a small toy mouse. A black one with a pretty golden bell attached on the base of its tail.
Gently nudging it towards the demon with his paw, Butter lays down, choosing Mammon’s bed to be the place to be tonight.
Picking up the disgruntled mouse toy, Mammon sighs, laying down, a soft orange cat snuggled into his chest, purring and warm.
Perhaps purrs are healing, because Mammon awakes in the morning from a dreamless sleep, no cat in sight but the little black mouse still sitting on his pillow.
Leviathan
He’ll be honest, they give him anxiety.
What if they knock over his shelves? Oh no, what if they damage his limited edition figures?! Tear his manga?! No! No cats. None.
You didn’t raise particularly obedient animals however.
After a long day of attending R.A.D, Levi quickly scurries into his room, already stripping off the complicated uniform.
Kicking his shoes that way, throwing his jacket over there, all the way down to boxers as he looks for his hoodie and ohmydiavolo the cats are on his gaming chair.
Unblinking, unmoving, as a demon stands practically naked before them, perfectly content as tofu sits on the back of the chair and butter sits on the seat.
“Get- you-” Leviathan scrambles for a hoodie, a blanket, a pair of pants, anything. Eventually finding himself far more prepared in a blue hoodie and black plaid pajama pants.
“Could you-” he stands nearly five feet away from the cats, almost scared to get closer, “just, leave? Like, out the door?” he gestures to the door, they don’t move.
Frustrated and unsure of how to handle this situation Levi just sort of… stares at them for a few minutes, until eventually, by some miracle, Butter gets up.
Stretching his little booty high in the air as his front claws gently prick the seat, making Leviathan wince, he jumps off the seat and makes his way to the tub.
Gently placing his front paws on the rim, he looks over the edge before deciding this is the exact place he needs to be and jumps in, spinning around a few times before sitting down and placing his head on his paws.
Leviathan, deciding to choose his battles, turns back to Tofu, "just don't move, okay?”
Slowly and carefully, Levi sits in the gaming chair, putting on his headphones and botting up his system.
Tofu doesn’t seem to mind, tail slowly flicking back and forth, occasionally brushing past Leviathan's cheek, causing him to tense for only a moment.
In the end, she’s quite a good gaming partner and Butter has found his favorite bed.
Satan
It was obvious how Satan was going to react when the brothers found out two cats were moving in.
He was absolutely ecstatic, practically vibrating from excitement, and he was one of the first to meet the little critters.
Due to the large environment change, you wanted Tofu and Butter to have the chance to slowly acclimate to their new homes.
Understand the new smells, noises, temperatures, daylight cycle, everything. So for the first few weeks they stayed in your room, occasionally venturing into hallways when most people were out or exploring when the house was empty.
Satan happened to be home when they explored one time.
Exiting his room and walking to the kitchen, Satan goes to prepare a study snack, yet he is stopped dead in his tracks when Butter and Tofu sit at the entrance.
Lounging around, Butter has stretched himself as long as his little body can go, Tofu remains in a rather dignified loaf, both watching Satan.
Safe to say all plans on food and studying get thrown out the door. Slowly, as to not make any sudden movements, Satan lowers himself to sit on the floor, barely two feet away.
“Hello,” he practically whispers, slowly getting down to lay on his stomach, thank diavolo none of his brothers are home, “aren’t you two darling?”
Satan tentatively reaches a hand out, placing it delicately on the floor in front of the kitties, close enough for them to sniff if they choose, far enough they can turn away.
Butter seems to watch Tofu, who gets up from her loaf, stretching as he claws scratch slightly against the tiles. She takes a step and gingerly leans her head down, sniffing Satan's hand.
He sits there with batted breath, frozen in place.
It's hard to tell how long Tofu judges his entire existence, but she decides he is worthy and licks his hand, rubbing against his arm as she walks closer.
“Hi, honey.” Satan smiles, petting Tofu as she rubs all over him. Butter follows her lead, getting up and invading any form of personal space in an attempt to get as much attention as possible.
The study session does continue, but now with two cats in his bedroom.
Asmodeus
Cats are cute, that's true.
But, much like Mammon, Amsodeus hates how much they shed.
Those sheets cost more than any mortal makes in their life and now there is cat hair all over it!
Plus the smell, the grooming, and the shitting in a box has never been very… appealing to Asmo.
Unfortunately for Asmo, Butter loves his private bathroom. Maybe Butter just likes tubs, but sitting on the porcelain, stretched out as he naps, seems to be a favorite pastime of his.
Asmodeus hums to himself as he walks into his private bathroom, wrapped in a pink silk robe with feathers on the ends, a green face mask setting into his skin and fluffy pink slippers.
Walking to one of the large and ordained shelves, he picks up a few different products for the water, flower petals, skin care products and hair care products.
Sitting down on the edge of the tub and placing them next to him he moves to turn on the faucet but is stopped by an orange mass.
“Oh!” taking a sharp intake of breath, Asmo pulls his hand away from the faucet, instead reaching out to gently tap butter's forehead.
Letting out a small prrrrt, Butter blinks open his eyes, dilated as he looks at Asmo.
“Well aren’t you a cutie?” Asmodeus giggles, watching Butter get up and walk to him, “I’m trying to take a bath here, ya know?”
Butter doesn’t seem to care, hopping up onto the large edge of the tub and making that his resting place instead.
Deciding this little kitty shouldn’t be the reason he doesn’t complete his routine, Asmo continues to fill the tub, but changes some of his products out, unsure of what could hurt mortal cats.
Butter exits the bathroom over three hours later, brushed and pampered, quite a handsome boy.
Beelzebub
Beelzebub was rather indifferent about Butter and Tofu. although it did have to be explained a few times that they are not made of Butter and Tofu and ‘please don’t eat my cats.’
Fortunately, it seems they share a love for food.
It’s late, like extremely late, but Beel’s stomach said it's food time, so now he finds himself in the kitchen, shirtless as he sits on a stool, eating his findings.
Halfway through, two sets of teeny tiny claws prick his calf.
Quickly looking down, at his feet sit the infamous kitties of The House of Lamentation.
Butter stands on his hind legs, reaching up Beel's leg and meows, begging as if two bowls of wet food and two bowls of dry food don’t sit right behind them.
Tofu chirps, rubbing her body against his legs, looking up at him with big, begging eyes. Butter is far more dramatic, practically wailing and begging like he isn’t the most spoiled tabby in all of Devildom.
But they are so cute… but they shouldn’t eat demon food…
Beel stands up, trying not to trip over the cats who swarm him like sharks as he looks for their treats.
There is definitely more of a variety than he thought, from salmon to chicken to soft to hard to teeth health to hair health, Barbatos really stocked up…
He picks out a few, remembering the warning of not over feeding the cats as he pours some out into his hand, trying one of each himself (Not bad, he’s eaten worse, he gets why cat’s like them), before crouching down and placing two piles on the ground.
As the two cats attack the piles of treats (that they will eat too fast and throw up in your room later), Beel returns to his munching.
But!! Barely three minutes later they are begging again! Butter is practically climbing Beelzebub like a ladder to steal his food!
Are all cats like this?
Belphegor
Belphie told everyone he didn’t care about the cats. Whether they liked him or not, he doesn’t give a fuck.
But he really wanted them to like him. Like so bad. It's pathetic honestly.
He’s always seen videos of those cuddly cats who sleep in humans arms, and dogs who sleep at the end of the bed, and he really wants that.
He wants Tofu to snuggle up in his arms, she looks so soft and fluffy. And he wants Butter to lay on his chest, slowly kneading.
One night, Belphegor is resting in the planetarium, laying on a nest he made on the ground as he lazily gazes at the night with half lidded eyes.
Falling in and out of sleep as the stares pass his vision, unbothered and uncaring. Until a cat comes, obviously.
Stepping her little feet carefully on the pillows and blankets surrounding the demon, Tofu tentatively walks over, rubbing her face against Belphie’s.
Gently, he scratches behind her ear, feeling her purr and chirp before laying down, head nuzzled into his neck, tail curled to flick over his collar bone.
A few minutes later, with the never ending need to annoy his older sister, Butter finds the pair, cozy and warm.
Stepping his front paws onto Belphigor’s chest, he hoists himself up, gently patting Belphie’s cheek to get his attention. Content when an eye opens to peak at the orange cat.
Happy and pleased with the minimum disturbance he caused, butter lays down, Belphie’s free hand moving to rest on Butters back, gently stroking as they fall asleep.
