Here's a dose of dopamine for you.
NSW-based sister organisations Aussie Ark and the Australian Reptile Park decided to brighten Monday up a bit by releasing pictures and video of a recent "devil daycare" play session, involving four adorable, six-month-old Tasmanian devil joeys.
The joeys - Indigo and Violet from Aussie Ark, and Charlie and Lola from the Reptile Park - had "a blast" once they left their comfy blankets, romping with each other and wrestling with toys and blocks before settling down for a cuddle and a bottle-feed.
To keep the joeys entertained, the keepers also placed meat inside logs for them to find, helping them develop their natural instincts for the wild.
The joeys were also given the opportunity to play with each other, which is important for their socialisation and development.
In 12 months, all four joeys will make their return to Aussie Ark and be released into a protected wildlife sanctuary - the largest of its kind for Tasmanian devils.
There they will be able to join the breeding program devoted to saving the iconic Australian animal.
Aussie Ark's population of Tasmanian devils are free from the devastating devil facial tumour disease (DFTD) that plagues wild devils, and is the largest population in the world.
"Seeing these joeys play and grow is a reminder of why we do what we do," Reptile Park keeper Lauren Hunter said.
"Lauren and I are happy to report that they absolutely adored one another," Aussie Ark ranger Tyler Lowe (pictured left with Hunter) said.
"The outcome of the play date is exactly what we wanted."
The sister organisations are involved in vital conservation breeding projects to help save threatened Australian species, including the 400 hectare devil sanctuary.
Meet Albert - the tiny koala joey that almost didn't make it.
The joey was born at the Australian Reptile Park on the NSW Central Coast five months ago.
Two weeks ago, the park's koala handler Hayley Shute intervened in an urgent rescue to save both Albert and his mother, Elsa.
At the time, Albert weighed just 190 grams but with round-the-clock care he has gained over half his body weight to weigh 312 grams. He's even started eating eucalyptus leaves.
The tiny joey was affectionately named Albert, after his charmingly elderly appearance.
He is the smallest koala joey to ever be successfully hand-raised at the Australian Reptile Park.
"It melts my heart to see Albert thriving, considering the first time we met he was at risk of not making it," Ms Shute said.
"I was definitely worried, but I know he's a fighter just like his mother.
"I'm happy to report that Elsa is doing well and is on track to make a full recovery.
"In the next six months we will have the pair reunited with each other and the other koalas at the Park."
Koalas were listed as endangered last year, after their populations were devastated in the 2019-2020 Black Summer bushfires.
They are estimated to become extinct by 2050 without urgent interventions.
Conservation group Aussie Ark has released a brush-tailed rock wallaby named Rocket into its brand new enclosure.
Rocket has been handraised by staff at Aussie Ark, including operations manager Dean Reid, since April.
"Today is an emotional day for me; I'm really happy but also a little bit sad," Reid said.
"It's been a long journey to get Rocket to this point, and when you've hand-raised an animal you get attached to them."
Rocket is now part of Aussie Ark's rock wallaby breeding and rewilding program.
There are only 30,000 of his species left in the wild.
"Once Rocket is settled we'll introduce him to a girlfriend," Reid said.
"And we hope for many more little Rockets bouncing around in the future!"
His enclosure is made up of rocky mounds, tree branches and spaces for dens.
A platypus puggle rescued on the NSW Central Coast has been named Matilda, after the Australian women's football team.
Tilly, as she's known, was admitted to Taronga's Wildlife Hospital in April 2023 after being found under a bush covered in ticks and severely malnourished.
She was about four months old at the time and her poor condition compromised her waterproofing, making it difficult for her to swim and survive on her own.
Following around-the-clock care, the now eight-month-old is able to eat and forage on her own.
The zoo's expert platypus team hand-fed Tilly six times a day for two months and her condition started to improve.
"Tilly would have weighed a tiny 1.5 grams when she hatched from an egg the size of a marble," Taronga Wildlife Hospital veterinary resident Dr Jess Whinfield said.
When she arrived at the wildlife hospital, the puggle weighed only 280 grams.
Following her recovery, she recently weighed in at 694 grams.
In a statement announcing the cute creature's rescue and new name, the NSW government said: "The name Matilda means 'bold, battlefield warrior' and represents both our mighty women's soccer team and Taronga's puggle who is going from strength to strength."
Three lion cubs born at a Victorian zoo have been given names.
The precious 10-week-old cubs are continuing to grow in both size and confidence at Werribee Zoo.
Meet 10-week-old cubs Mwezi, Kianga and Jango who have certainly mastered the art of play fighting.
The names, which translate to moon, sunshine and brave in African languages, have been chosen following a vote by more than 300,000 zoo members.
The cubs are continuing the grow everyday, according to Werribee Open Range Zoo African River Trail Keeper Ben Gulli.
He said the cubs have been taking opportunities to explore the comforts of their den, while venturing into their pride's habitat.
But just like newborns, the cubs tire very quickly.
The trio of African lions are expected to increase their strength and resilience in the coming weeks and months.
The species are facing threats to their population, declining to around only 39,000 in the wild in sub-Saharan Africa.
A giant panda has given birth to twin cubs at a theme park in South Korea.
Ai Bao gave birth to the cubs, both female, last Friday at the Everland theme park near Seoul, the park's operator, Samsung C and T Resort Group, said in a statement.
It's the first time that panda twins have been born in South Korea, the resort group said.
Both Ai Bao and her newborns are in good health, it said.
Decades of conservation efforts in the wild and study in captivity saved the giant panda species from extinction, increasing its population from fewer than 1000 at one time to more than 1800 in the wild and captivity.
The life expectancy of a giant panda in the wild is about 15 years, but in captivity they have lived to be as old as 38.
The South Korean resort group said it will observe the cubs' health and growth conditions to determine when to unveil them to the public. Meanwhile, the group said it will use social media to show off the cubs.
Ai Bao and her male mate, Le Bao, also a giant panda, came to the park in 2016 from China on a 15-year lease. In 2020, Ai Bao gave birth to a female cub named Fu Bao.
Ai Bao, Le Bao and Fu Bao had been the only pandas in South Korea.
Everland's Panda World, which houses the three pandas, has received 14 million visitors, according to the resort group.
Werribee Open Range Zoo in Victoria has welcomed a healthy litter of three lion cubs, the first of the threatened species to be born at the zoo in almost six years.
The cubs were born on Sunday evening weighing about 1.5 kilograms to 11-year-old mother Nilo and five-year-old pride male Sheru.
