Announcement dated September 3, 2023
As previously announced, the female Sumatran Tiger cub, which was switched from assisted feeding to artificial feeding on May 28th, now weighs 9,300g as of August 31st, 2023.
Sumatran Tiger cub
(Photo taken on August 31, 2023)We started giving the cub small amounts of minced horse meat on June 12th to wean it, and we've been gradually increasing the amount as it grows. Lately, when we give it chunks of horse meat, it has started to bite and eat them skillfully with its molars, just like an adult tiger. Its physical abilities are also developing well, and it can easily go up and down stairs. In addition, it is exhibiting many tiger-like behaviors, such as scratching its claws and sneaking up to toys in the room before pouncing.

(Photo taken on July 31, 2023)Even during the meeting with Manis (female) across the bars, he didn't seem afraid of Manis; he would peek into the adjacent bedroom on his own, rest near the bars, and so on.
On the other hand, several tests conducted for health checkups have revealed a suspected congenital kidney abnormality. Abnormal values have also been observed in blood tests. Although the baby's weight is low for its age, as mentioned above, the child is growing healthily, so we will continue to monitor its condition and conduct further tests and treatments.
The name is,
We named it "Asa," which means "hope" in Indonesian. It embodies two wishes: that it will be a source of hope for the future breeding of Sumatran Tiger, and that it will grow up healthy and strong, overcoming any congenital diseases. It also matches the name of its mother, "Mimpi," which means "dream" in Indonesian.
Going forward, we will gradually begin practicing bringing the animals out into the exhibition hall in preparation for their public debut. Once the opening date is decided, we will post it on our website.
