3-year-old Belle wakes up cradled softly in the arms of a teenage calico cat. This is unusual for the bunny girl, as the big kids usually don't seem to care much for her, or any of the little ones for that matter. She certainly doesn't mind it, though. 
The teen girl smiles down at Belle warmly as she stretches out in her arms and relaxes. It's warm and cozy, and this girl isn't trying to play with her in weird ways like the grown ups always are. Frankly, it's a nice change of pace.
Belle can't help but wonder, though, why this older kid suddenly took a liking to her.
GRRRGGGL... BLRRP PFFFFRRRRT...
In the late hours of the night, Belle slept alone sprawled out on her back on the padded floor of the main holding area in a nice, secluded corner. Her tummy groaned and gurgled as it finished processing an enormous meal that now took the form of mush ballooning out a massive, bloated gut.
The mulched remains of a caretaker, Samantha, pushed through her and began to pass out her backside. The bunny didn't even stir as she began to load her diaper with fat logs of former fox.
FBLRRBFBLFRRRT CRINKLE FBLRRRFBT CRK
Immediately, the diaper and onesie backside surrounding it began to grow as huge amounts of little girl poop were forced into them. The mound of brown filled it to capacity in mere seconds.
PFFRRRRR BLFLBRBFRFFBLRRCKLRRR CRINK 
Samantha's bones were forced out into the diaper along with the scat that used to be her flesh. Femur, ulna, tibia, and pelvis were all violently shoved out of the toddler's rear end as the diaper ballooned out further and further. The fox's entire spine snaked its way out, barely held together, and the sound of the little girl's bowel movement had grown to a flatulent roar.
Finally, as the diaper had grown into a bean bag chair-shaped thing larger than Belle herself, she passed the gas that had been choked down along with the caretaker in one cacophanous fart, followed by the last bits of poopie and Samantha's skull.
PPPFFFFFFFFRRRRRRRRRRRRRRTTTRRRBLRFHBLG SPLRCH
As the little girl reclines in the calico's arms, she can't help but notice how soft and clean the onesie she's wearing is and how her diaper is fresh as well. She wonders how she got into this fresh change of clothes.
Her attention is briefly pulled away by a group of grown-ups in a different corner of the room. They're huddled around each other, each wearing a usual caretaker onesie, and they seem very deep in conversation. Occasionally, one glances around the room before turning back to the group.
Belle wonders what they're talking about.
PFRRT BLORT
The toddler's bowels were finally settling down as she laid still on the floor, sleeping peacefully as though nothing had happened. Nearly all of the other children, if they weren't already awake by then, had been awoken by the small girl's cacophanous diaper messing. They congregated in a circle around her with wide eyes, whispering amongst themselves.
Finally, the eldest of the group, an 11-year-old gazelle, took initiative for them. "Quick, get her out of her clothes, or she'll get caught for sure," she said.
The children did a rather poor job, uncoordinated as they were, but ultimately they got the job done. With a bit of smearing on her legs, they'd gotten the bunny out of her onesie. After such a big meal, though, she was still sleeping very heavily.
"Let's hide her, quick," the gazelle suggested. The group settled on taking her to the reading room, and they carried her as quickly as they could before setting her down behind a bookshelf and going out to see what will happen when the next rotation of caretakers arrived.
It wasn't long before the last remaining caretaker on the night watch, a tiger lady, was simultaneously woken up from where she'd carelessly fallen asleep beside the outter wall of the main holding area and relieved of her watch duties. 
The following group of caretakers was much larger, and they entered with the procession of the babied teenagers who'd been forced to sleep in the cribs. Breakfast duties would have to wait, though, as they quickly saw the unmistakeably adult-sized mound of shit and bones wrapped up in a discarded diaper and onesie nearby.
The caretakers quickly dialed security to report the incident and begin to work out which child had done the deadly digestive deed. Meanwhile, the teens slinked off to figure things out for themselves.
It wasn't hard for the calico girl to find the culprit, naked and with a poopie butt sleeping behind a bookshelf. She briefly debated what to do with her, but then she quickly decided not to let a caretaker-eater get caught.
And so the calico girl lifted up the little bunny and quietly made her way to the showers and changing room.
Belle yawns and gives the calico girl a friendly nuzzle. It's nice to be held without being groped or molested for once. She still isn't sure what happened last night, but the grown-ups seem to be dispersing, and nothing else seems to have come of it.
The little bunny relaxes; she's entirely carefree and barely even cognizant of what happened, but at least she had a nice, big meal.
A couple small investigations will be held in the coming days, but ultimately no blame will be cast on caretaker or child. Samantha's death will be chalked up to error on her part, not properly minding a workplace hazard, and Child Servers will move on.
