Not sure about the attacking offspring point. Cleo's mother drove her out at a few months old according to the lady who had her before me, hence her being semi feral for the month or so before I got her. As for the masturbating, Murr, bless him, used to try to do what dogs do to your leg to my arm.:-)
Of course domestic cats are not "wild" animals, although I beleive scientists recently reclassified them as felis silvestris cattus as much of their behaviour was so similar to the European wildcat, as , apparently is their DNA.
