Is my Bioluminescent, Four-legged, Bat Creature Possible?
Note, all animals are actually only Damarian equivalents of the animals named, except for my question creature.
My world, Damarian (Found in my newer posts), has a species of obligate carnivores, called Avari. They're mostly Mesolithic, but some have advanced to be up to Bronze Age equivalent (Also, some went to more advanced areas to live with non-Avari, adopted, or married a fellow Avari who grew up in the more advanced areas). They're allergic to iron, so Bronze Age is as advanced as they can be (For now).
The Avari domesticated wolves and made dogs, but even the Bronze Age Avari use dogs mostly as guards and for combat, not as companions. Regular barnyard animals (Chickens, Cows, Bees, Sheep, Pigs, Goats, Horses, Donkeys, etc.) are kept for food and animal byproducts (Milk, Eggs, Honey, Wool), due to Avari being obligate carnivores (Also felinoid). Horses and other large beasts like donkeys and llamas are used for mounts and pack animals, while cows and oxen were also used as plow pushers. 162
Bees are used for honey (Which they use for a version of sugar they love) and beeswax (Used for candles), along with novelty defense (And pranks). They never domesticated cats, but they tolerate them, as they eat rats, mice, and other vermin that eat the straw for their other animals.
This, therefore, means that the Avari don't have real pets. However, they do.
Not dogs, not cats, not even birds, but BATS.
Little, bioluminescent, four-legged bats about the size of two IPhones 12 (29.34 cm long, and about three times that wide for wingspan), called Niywits (nee-WITT).
Here are the features of Niywits:
* Eat insects and small berries primarily, but enjoy little bits of cooked meat and egg as treats (Most Niywit experts of more advanced regions recommend only giving them a few grams each week). <PERSON> give them about the same amount recommended because their little friends get sick after eating too much of them.
* Typically blue, steely grey, and black, with short fur (Abroad, they're bred to have longer fur and different colors).
* The face area (From in front of the ears, to chin, in a circle), has no fur, and the wing membranes also have no fur. They have blue, yellow, or green eyes.
* Bioluminescent in the wings (Along the bones in rows of dots, and running halfway up the wing in the shape of the trailing edge in rows of dots), face (Spots on the eyes and outsides of the ears), and hidden in the fur as stripes (Makes cute green stripes on the Niywit).
* Sexually mature at 3 years old (Niywit equivalent to an 18-year-old Aerithean), live up to 12-14 years old (Roughly 72-84 year-old Aerithean), but can only breed up to 9 years of age (54-year-old Aerithean), with actively breeding males and females ending their breeding careers a year-ish earlier.
* Females have a single litter every year, gestating for 24 days (3 weeks Damarian time, 3 1/2 weeks Earth time), giving birth to 1 or 2 nibs/pups (The term for baby Niywits), nursing them for the first 9 months of their lives.
* Breeding season for Niywits is from March to May for Damarian (96 days, or March- first 4 days of June on Earth), when the tropical regions of Dendar (Where Niywits and Avari evolved) are transitioning from the dry season to the wet season.
* Niywits are polygamous, in the sense that they do not take a permanent mate; Males only stay with one female for breeding long enough to conceive offspring, then the female rears the nibs with other females.
* Niywits are social creatures, preferring to live in groups numbering anywhere from 3 to about 12 Niywits. Fortunately, they don't need much food (Only some bugs and a couple berries or tiny grapes a day), so most Avari keep numerous Niywits simultaneously.
* Have camouflagable skin, which, combined with their ability to control the color and brightness of bioluminescence, creates a somewhat hypnotic effect (But see next two bullets). 802
