[Space] Social Pouncing Carnivores?

[Bruno]

You don't need to be social while gathering food to be social. Housecats are the posterchild for this - they form colonies into the hundreds if there's enough food, they practice collective childrearing, social grooming, collective play as adults (without human contact)...

Housecats may have been manipulated by humans into becoming this social pouncing carnivore, but they're still a good example. They also provide an example of what might prompt this sort of stage in a species development - have a source of pouncable prey exist "in the thick" of a larger, highly social species that considers the prey to be undesirable parasites and the predator to be minimally-threatening.
