feral cats tend to form colonies but wild cats are solitary, like the european wildcat: https://en.wikipedia.org/wiki/European_wildcat

Housecats are descended from the African wildcat, not the European one. The African wildcat forms colonies just like housecats.

Much of the myth that cats are naturally solitary creatures comes from people studying the behaviors of the European wildcat and attributing them to housecats, which is wrong because that's not what housecats are descended from.
