Male Tigers with Cubs

[Pckts]

We can't say whos a better father between tigers and lions. They live completely different lives, lion cubs have a entire pride to take care of them, Male lions don't need to be a good father, but they still tolerate, protect and let them feed on kills with them.  
Tigers have only mother and father, and in T25's case, only father to take care of them. Tiger males have no choice but to be "better fathers" because without them, these tiger cubs have a very slim chance of surviving to adult hood without a prime males protection. 

I think we all know by now that Male tigers are extremely good fathers and protectors. 
Shivaji is another tiger that comes to mind. 

I think that where the higher intelligence factor really comes in, is the tigers ability to take advantage of situations that are presented and also being able to survey a situation and learn from it. Like sneaking through a fenced off area, grabbing a cattle calf and instead of eating it there where the villagers are, he takes it back under the fence, walks around then makes off with it. Almost like a serial killer trying to avoid being caught by the police.
I'm sure it also plays a role in raising cubs as well, but usually most animals are great parents. Maybe not every time, but I would bet that wild animals are far more effective parents than humans are. Reply
