I agree with this, Snow. I definatly think Zira made sure that Kovu got more than his share of food to ensure that he would grow big and strong, not thin and under-nourished. With food already being scarce and hard to find, I think this would indeed put a lot of strain on the pride, and undoubtetly cause conflict.
Also, remember when Kovu and Kiara were stargazing? Kovu saw an image in the stars that looked "like two lions killing eachother over a scrap of meat." Sounds to me the Outlanders were pretty desperate to get any food they could.
Looking at the Outlanders, it looks like Kovu is the only one with a strong, full build. All the lionesses, even Zira and Vitani are really skinny, a sign that they have been getting way too little food.
I’m sure Zira made Vitani and Nuka give up a lot of their food to Kovu.. When it comes to Zira herself, I feel like she could live off hate alone.
