Knut was the orphaned polar bear cub raised in captivity that stole everyone's heart. Knut passed away in March at the age of 4 in Berlin when he suffered an illness; encephalitis. The latest polar bear cub, "Siku" to be born in captivity was orphaned by his mother, so he is being raised by hand in a Denmark Wildlife Preserve. He is only 5 weeks old and seems to be enjoying all the attention he's receiving. It's hard not to fall in love with this little guy.

Siku whish stands for "sea ice" is only 5 weeks old being born on November 22nd and weighs 7lbs. He resides at the Scandinavian Wildlife Park in Denmark. His mother did not produce milk and was in jeopardy of starving to death, so zookeepers chose to bottle feed the little guy. He's doubled his weight since birth; as an adult he will weigh as much a 1/2 ton. Siku is loving all the attention he's getting. He loves rolling around, taking naps and sucking on his keepers fingers.

Siku will be pampered and will never return to the wild. He will be part of a large breeding program and will join 4 other adult polar bears when he turns 2. He will also serve as an ambassador for polar bear preservation. There are only about 20,000-25,000 polar bears left in the wild and due to ice cap melting those are endanger of disappearing.
