The only creatures in teen wolf with yellow eyes are werewolves Which is making the assumption that all werejaguars have the same color eyes. Which is kind of silly, since we know werewolves have three different color eyes. There's a lot of pretty severe differences between the kind of werejaguar that Kate is and the kind of werejaguar that Hayden is. For example, Kate is a murderer -- something we know changes the eye color of werewolves -- and Hayden is not.

We also know werecoyotes have the same eyes as werewolves, so those "werewolf eyes" are clearly not an exclusive thing.

So, again, I don't feel that just seeing the eyes is 100% proof that Hayden is part werewolf. You can make that assumption but until someone comes out on screen and tells us that Hayden is part werewolf, it's just an assumption.
