00:00:09,709 --> 00:00:11,336
We're off to California...

2
00:00:11,411 --> 00:00:14,437
where the San Diego Zoo and
Wild Animal Park

3
00:00:14,514 --> 00:00:18,746
is finding new ways to raise wild
animals.

4
00:00:18,818 --> 00:00:22,254
Here's a sight you're likely never
to see in the wild.

5
00:00:23,656 --> 00:00:27,888
A puppy and a lion cub playing
together, peacefully.

6
00:00:30,463 --> 00:00:34,661
Koza was separated from his
mother at birth...

7
00:00:34,734 --> 00:00:38,226
so keepers put him together with
a puppy named Cairo

8
00:00:38,304 --> 00:00:41,000
so he would have a companion.

9
00:00:43,376 --> 00:00:46,436
Randy Rieches works at the San
Diego Zoo.

10
00:00:46,513 --> 00:00:49,641
He says many wild animals are
social creatures...

11
00:00:49,716 --> 00:00:51,775
which means that when they are
young,

12
00:00:51,851 --> 00:00:54,479
they need to learn to get along
with others.

13
00:00:54,554 --> 00:00:57,455
In any instance where you have
a social animal,

14
00:00:57,524 --> 00:01:01,551
it's always better to pair
something specific with that animal

15
00:01:01,628 --> 00:01:06,895
to actually help that animal
psychologically progress into
adulthood.

16
00:01:09,135 --> 00:01:13,765
For years now, the San Diego
Zoo and Wild Animal Park have
been pairing

17
00:01:13,840 --> 00:01:18,243
lone wild animals with different,
but compatible, species.

18
00:01:18,311 --> 00:01:22,304
Majani the cheetah and Clifford
the dog are old friends.

19
00:01:22,382 --> 00:01:25,249
They were put together as
youngsters years ago...

20
00:01:25,318 --> 00:01:27,843
and now the shy cat feels comfortable

21
00:01:27,921 --> 00:01:31,721
when out in public with his
canine companion.

22
00:01:31,791 --> 00:01:34,624
This young Indian rhino liked to
play...

23
00:01:34,694 --> 00:01:37,094
so keepers found him a playmate,

24
00:01:37,163 --> 00:01:40,963
a banteng, a type of large cow.

25
00:01:41,034 --> 00:01:44,333
Someday this rhino will grow to be huge,

26
00:01:44,404 --> 00:01:47,601
weighing about 1800 kilos,

27
00:01:47,674 --> 00:01:51,542
while the ox will only be about 700.

28
00:01:51,611 --> 00:01:54,808
But keepers say animals like
these are kept together

29
00:01:54,881 --> 00:01:58,339
as long as they enjoy each
other's company.

30
00:01:58,418 --> 00:02:01,512
And the rhino will learn social
skills he'll need

31
00:02:01,588 --> 00:02:05,080
when it's time to be introduced
to other rhinos.

32
00:02:07,160 --> 00:02:11,790
On the other hand, Koza and
Cairo will soon be separated.

33
00:02:11,865 --> 00:02:13,799
Lion cubs grow quickly,

34
00:02:13,867 --> 00:02:17,030
and today's companion could be
tomorrow's prey.

35
00:02:17,103 --> 00:02:22,405
You have a lion which is a
predator, a very large predator,

36
00:02:22,475 --> 00:02:26,502
that at some point in time,
we will have to split them.

37
00:02:28,314 --> 00:02:32,216
Cross-species friendships don't
happen in the wild...

38
00:02:32,285 --> 00:02:37,848
but they are used sometimes in
zoos as a way to keep social
animals... social.
