I was domesticating wolves and ocelontes in my minecraft pocket edition on my cell verykool S353 ..

What I expected to happen it was ... :
Tame wolves and ocelontes and save my departure ( world).

What actually happened was ... :

Steps to reproduce:
1. Find a wolf and ocelonte
2. tame .
3. When entering my departure observe my pets not standing estanban, without defending How I'm supposed to defend the enemies ?
