Sumatran tiger Damai gave birth to two Sumatran tiger cubs on Monday evening, August 5, 2013! These cubs are a conservation success. Sumatran tigers are critically endangered in the wild, so every cub counts.
Damai gave birth to the first cub around 6:15 p.m. and the second around 8:23 p.m. Keepers have been monitoring the cubs and both appear healthy. Damai is being a great mom, and is nursing and grooming both cubs.
We are giving Damai time to bond with and care for her cubs. They most likely will not be on exhibit until late fall. In the meantime, you can watch them grow on the Zoo’s tiger cub cams!
January’s bouts of winter weather have kept our tiger cubs, Bandar and Sukacita, on their toes! The cubs seem to have a heap of fun pouncing in the snow. While we want them to enjoy their time outside, we are mindful to let them out for just a short time. That way, they aren’t overexposed to the elements. Given the opportunity, they would probably play in the snow all day! Their parents—who have experienced snow many times over—tend to spend less time in the snow and more time in the comfort of the heated dens. We are training the cubs to come inside when the shift door opens. So far, they’ve been responding well, especially because they know their reward for doing so is a tasty beef chunk! Days when the temperature is in the teens and single digits, we keep the cubs inside. Mom and dad, though, have the choice of whether to go out or stay in. So, if you visit on a day that is not quite so bitterly cold, there is a good chance you’ll see them in the yard!
Bandar and Sukacita are nearly six months old. They’re still at the age where playing with each other is their favorite source of entertainment. On those colder days when the cubs are inside, we’ve also introduced them to some youngster-friendly enrichment—objects such as smaller versions of the adults’ boomer balls, balls with catnip inside, logs with different scents—and they seem to have a good time batting then around. Luckily, the cubs’ little teeth and claws are much more gentle on their toys than their parents’ are! If you’d like to purchase toys for the growing cubs, check out our Wish List. They’ve started basic target training and are both very enthusiastic students—so enthusiastic that we could not get a picture of Bandar that is not blurred or one of Sukacita sitting down!
Bandar and Sukacita have started basic training—shifting inside when called and teaching them to eat on their own and become less dependent on mom. We haven’t observed nursing for some time now, so we are almost certain they’re weaned off Damai’s milk. As part of their diet, they each eat about 2.2 pounds (1 kilogram) of meat per day, which is 15.4 pounds per week. They’re gaining weight steadily and, as of last week, Sukacita weighs about 51 pounds and Bandar weighs about 60 pounds. They’ve doubled in size since their November debut!
Thinking ahead, we’ll be watching the cubs’ interactions with mom and each other in order to determine the best time to separate them. Usually, tigers start showing signs that they’re ready around 1 year old. We will have more updates, photos, and videos as the weather warms!
Our Sumatran tiger cubs just turned four months old! Bandar and Sukacita quickly took to their yard. In fact, the first day we opened the door, both cubs fearlessly bolted out—climbing, hiding in the bamboo, and trying to sneak up on mom Damai (and each other)! They’re great fun to watch. Right now, the best time to see them is from 10 a.m. to 11:30 a.m. every day, depending on the weather.
Behind the scenes, keepers have started basic target training with the cubs. In target training, we ask the cubs to move the body part to the end of the target. We are starting with just one command—the cubs must touch their nose to the end of the target—and, so far, they’re doing really well. This is the building block for other behaviors that will help animal care staff evaluate their health.
Damai's two cubs Sukacita and Bandar will have access to the yard and will be on exhibit to the public for the first time today at 10 a.m.!
As they are still quite young, the tiger team anticipates that they will be on exhibit for about one hour. They will be on public exhibit each day but this may vary depending on the weather and on the animals themselves.
Our two Sumatran tiger cubs took a brisk doggy paddle at the Smithsonian’s National Zoo today and passed their swim reliability test! The cubs also now have names: the male is Bandar and and the female is Sukacita (SOO-kah-CHEE-tah). All cubs born at the Great Cats exhibit must undergo the swim reliability test and prove that they are ready to be on exhibit. Bandar and Sukacita were able to keep their heads above water, navigate to the shallow end of the moat and climb onto dry land. Now that they have passed this critical step, the cubs are ready to explore the yard with their mother, 4-year-old Damai.
“Tigers are one of the few species of cats that enjoy taking a dip in water,” said Craig Saffoe, curator of Great Cats. “The moat exists for the safety of our visitors, but it could present an obstacle for young cats. Our job is to make sure that if the cubs venture into the moat, they know how and where to get out. These cubs represent hope for their critically endangered species’ future, so we need to take every precaution to ensure their survival.”
Both cubs took the test under the guard of animal keepers Dell Guglielmo and Marie Magnuson, who gently guided the cubs in the right direction. The shallow end of the moat is approximately 2 ½ feet deep. The side of the moat closest to the public viewing area is about 9 feet deep and is an essential safety barrier that effectively keeps the cats inside their enclosure.
Friends of the National Zoo hosted an opportunity to name one of the Zoo’s tiger cubs on the website Charity Buzz. On Nov. 1, the winning bidder elected to name the female cub Sukacita, which means “joy” in Indonesian. The $25,000 donation supports ongoing research and education outreach at the Great Cats exhibit. Keepers selected the male cub’s name, Bandar, in honor of Bandar Lampung—a southern port city in Sumatra.
Starting Monday Nov. 18, keepers will decide on a day-to-day basis whether Sukacita and Bandar will spend time in the yard and for how long they will be out. This decision will be based on weather and how the cubs adjust to being outdoors. The Zoo will continue to share the latest updates and photos on Facebook and Twitter.
The cubs continue to grow and thrive. At this age everything can be a toy, including pine cones. This is the boy practicing his hunting skills with one while his sister watches. They had another round of vaccinations and as you can see in the picture of the girl, no one enjoys getting an injection. But she was a brave little tiger and now they are one step closer to going outside!
The shutdown has not affected the cubs at all—they didn’t miss a beat! Each day they are getting bigger and bigger. They had a wellness exam on October 15, when they received routine shots and vaccines. The male cub weighs about 21 pounds and the female weighs about 19 pounds.
Damai is spending more and more time away from the cubs during the day and rotating yard access with Kavi. She and the cubs have settled into a routine where the cubs spend most of the day in the cubbing den and all three spend the evening hours with mesh access next to Kavi. We are still hoping for a debut just in time for Thanksgiving!
Damai brings the cubs up to see Kavi most mornings now. Traveling around the building is a great way to develop their strength and coordination. We are even starting to see the cubs playing together. They are not very good at pouncing on each other yet, but it’s a lot of fun to watch them try! They are growing very quickly and the boy is a tad under 14 pounds while his sister almost 12 pounds. They are still getting all their nourishment from their mothers’ milk and that will probably not change for at least another month.
The tiger cubs continue to thrive and are steadily gaining weight. Their coordination is improving as well, and they are exploring all five of the rooms that are available to them. The little girl came out into the runway yesterday afternoon and saw her mother Damai engage in a training session with one of her keepers. Damai has shown signs of wanting to bring the cubs up to the mesh door to show them to Kavi. This is normal tiger behavior that we have been expecting. There is no webcam in this area, but we will try to get some video to show everyone when the cubs see their dad for the first time.

The tiger cubs are one month old today. And Damai has moved them back into a den on the tiger cam!
Our tiger cubs are 3 weeks old, and this morning they got their first veterinary exam—and passed with roaring colors. Veterinarians determined that the 2 cubs are a male and a female. The male cub weighs a little more than 8 pounds and the female weighs 7.5 pounds. During the exam the cubs received transponder microchips, and veterinarians collected blood and fecal samples from them. Veterinarians and keepers report the cubs are healthy, plump and growing quickly.
The cubs will not be on exhibit for several months until they have completed a series of four additional health exams, during which they will receive all necessary vaccinations.

Look at these pictures of the cubs the keepers got this week. The keepers can already tell which markings they'll use to tell the cubs apart.Can you find one or two distinctive markings to distinguish one from the other?

While Damai was enjoying a break from the cubs this morning, our keepers were able to continue desensitization training with them. And they were able to take some photos of them! The training is going well and will help get the cubs used to the keepers' smell and presence.
As you may have noticed, Damai and the cubs aren't on the cams at the moment. When she was pregnant, she had access to three possible cubbing dens, two of which had cams. Animal care staff did their best to make the two dens with cams as inviting as possible, to encourage her to stay there when she had her cubs.
Today, though, we opened up two other dens for her, which are farther back in the lion/tiger house as well as being a little darker. These are also the dens she was in for her quarantine period when she first arrived at the Zoo. She didn't move the cubs back there right away, but this afternoon she did choose to move the cubs back there.
Since she didn't move the cubs as soon as she was given the option, we do not think that her moving the cubs had anything to do with our keepers' sitting with the cubs as part of their desensitization training. If Damai had been upset about smelling the keepers on the cubs or the dens, she would have moved the cubs as soon as she had the chance. Since she waited, we think it's likely that she simply prefers those two dens as being slightly more comfortable, familiar, or protected-feeling.
Damai always has the option of moving the cubs back to the dens with the cameras, but we want that decision to be hers. Animal care is our first priority. We can't move the cams back to the den where she and the cubs are now. For the meantime, we promise to keep you updated with news and photos as soon as possible, and we'll be sure to let you know when and if she and the cubs move back to one of the dens with the live cams.
Damai came out of her den on Tuesday while keepers were in the Great Cats building, which is a good sign! That means she is comfortable with the keepers being near her cubbing den. While she was out she appeared very calm and stayed out for quite a while. She ate all of the meat keepers had offered her, and did not seem overly concerned about the cubs.
Eventually she made her way back into the den, and when she got there she didn’t move the cubs. That tells keepers that she didn’t feel anxious or threatened by their presence.
First time mom Damai is a natural with her two newborn cubs. The Sumatran tiger cubs’ eyes have not opened yet, so Damai is spending most of her time grooming and nursing them. Damai lets the cubs crawl all over her, as if her body is a jungle gym.
Damai is spending almost all of her time with her new cubs and who could blame her, they’re adorable! Bonding time is critical for mom and her cubs, so for a few weeks they will be off of exhibit spending time together. In the meantime, visit the cubs’ dad, Kavi, at the Great Cats Exhibit.
Not only are our two new Sumatran tiger cubs the cutest cubs in town but they are also a huge conservation success. With fewer than 500 Sumatran tigers in the wild, the birth of these cubs makes a stride in the direction towards saving this critically endangered species.
“It’s taken more than two years of perseverance getting to know Damai and Kavi and letting them get to know each other so that we could reach this celebratory moment,” said Craig Saffoe. “All I can do is smile because the team has realized our goal of producing critically endangered tiger cubs. Damai came to us as a young tiger herself, so it’s really special to see her become a great mom.”
Keepers and veterinarians began monitoring Damai closely in June after she began gaining weight and exhibiting behaviors that indicated she could be pregnant. Staff trained Damai to participate in ultrasound procedures, which allowed them to confirm her pregnancy on June 21, 2013. Keepers prepared for the arrival of cubs after Damai became restless and began showing signs that she would soon give birth. This is Damai’s first litter of cubs, sired by the Zoo’s 12-year-old male tiger, Kavi. The two bred several times from December 2012 through mid-April of 2013.
Tiger fans may be able to watch the newborn tiger cubs at the National Zoo reach every milestone for the next several weeks via live webcams on the Zoo’s website. Damai has the choice of moving her cubs to dens in the indoor tiger enclosure that do not have webcams. If she chooses to move them, they may not be visible on the webcam. Viewers can toggle between two webcams in the cubbing dens. During the next few weeks the cubs will open their eyes, become more mobile and potentially even start to explore the other dens that Damai can access.
