Certain feats are based on your heritage or bloodline, there are several different categories of these feats, but all of them are considered heritage feats, even those without the Heritage descriptor.
Creatures of the same creature type as a particular bloodline are considered to have the basic feat and a number of bloodline levels equal to their Hit Dice for the purposes of meeting the prerequisites of these feats; however, they do not possess an actual bloodline without gaining it in some way.
For example, a blue dragon with with 10 Hit Dice would count as having the Dragon Bloodline feat and would have a bloodline level of 10 for the purposes of qualifying for Draconic feats. He would still need to meet all other prerequisites of those feats. While he could take and benefit from the Dragonscale feat, he would gain nothing from the Dragonblood Inheritance feat, as he does not actually possess an ancestral bloodline.
Bonus feats granted by a bloodline count as Heritage Feats of the appropriate type. For example, a creature that gains Iron Will as a bonus feat from the Fey Bloodline counts Iron Will as a Fey Feat; however, if they took Iron Will as a normal feat choice, it would not count as a Fey Feat, even if the creature had a Fey Bloodline. The feat must be granted as a bonus feat by the bloodline to count as a feat of that type.
