There has been an update made public on Kamaia. His brother, Dinari, will be undergoing a procedure so that staff can collect blood that, if a match to Kamaia's, could be used for a transfusion. An "exploratory" surgery on Kamaia will be performed on May 9 to try and finally determine the cause of his anemia, where blood will also be drawn.
I hope everything goes well and Kamaia can be successfully treated.

"During tomorrow’s exam, the zoo’s veterinary team will draw blood from Dinari to see if it is a match with Kamaia, who is severely anemic, so that they can perform a blood transfusion. While there is always a risk whenever anesthesia is administered, Dinari is in good health and the team believes his risk is minimal for this short procedure, which could give his brother the best chance of survival.
On Friday, the veterinary team is planning to perform exploratory surgery on Kamaia, also age 14, to try to determine the cause of his serious ongoing health issues. If he is a match with his brother Dinari, a blood transfusion will also be performed."
"Last week’s exam included the collection of blood, urine, spleen and bone marrow samples, as well as X-rays of his chest and abdomen. The exam did reveal that Kamaia’s spleen is greatly enlarged, which could be the cause of the anemia he is experiencing although it is still unclear whether he has something more systemic affecting his health."
