This one's name is David. He got put into the hospital because of conjunctivitis, a form of chlamydia, a disease making that affects many koalas. He was getting fed a formula to help boost his energy.
This is another photo of David later on in the day.
This koala's name is Ocean Summer. Her mother was in a bushfire and she was in her mothers pouch. Her mother didn't survive but she did and came out with only some mangled claws. As she was only young she went home with an employee who acted like her mother until she was old enough to be on her own. She was not able to be released into the wild because she cannot climb trees without assistance because of her claws.
