Cliffy agreed all youngsters, (nothing older than 2,5 years most probably younger) most definitely not mature big cats very possible, I'd say, looks like a collection of gwarrie in the back ground or something similar I use to build Leopard blinds, mainly found clumped up together on river banks such as this one in the picture, anyone considered that the picture might have been taken shortly after a shower and possibly not around Phalaborwa but a little further SOUTH????
Male lion siblings often stay together after being forced to leave the pride by the resident dominant males, usually when they reach 2ï½½ to 3 years old. They will then live a nomadic life as young bachelors until old and strong enough to compete for a territory of their own, where they will have the benefit of working as a team in challenging a pride's resident male or males.
In super parks such as Kruger prides can consist of any number of lions research has shown that prides can total up to 40 cats.
Cool Pic Saeng, I say it is possible but thats just my opinion, thanks for posting.
