Nathan is turning into a real sweetie. He loves attention and follows me everywhere when I am outside. He will make a wonderful pet one day, but he still has a few feral habits I am trying to modify before I find him a new home.
He does what I call love nibbles (grooming nibbles???) but when he does these nibbles it hurts! And, he tends to scratch when I stop petting him and tackles my legs when I walk too quickly. This behavior has improved dramatically. He used to draw blood and does not any longer, but I fear this "loving aggression" would frighten someone not used to living with ferals.
BTW, for those new to working with ferals, the way I have been lessening his aggression is by simply hissing and blowing a puff of air in his face when he bites or scratches. I also praise him a lot and give him extra reinforcement whenever he walks with me without tackling or sits with me without nibbling. It is amazing how much improvement there has been in his behavior from these two simple techniques.
