Why Rock is Immortal

Rock is a nearly furless cat featured in the Omen of the Stars and The Power of Three series. He is a mystrous healer type cat, from the time of the Ancients. Rock has some supernatruel powers, and has the power to summon cats in his dreams, like Tree, and he has absolute knowlege of the past.

Rock is immortal because he is from the time of the ancients, and as of the last book he was seen in, Dovewing's silence, he is alive. This must mean that he can somehow achive a longer lifespan than an ordanary cat, espically a Warrior cat.

Rock also mentioned he was cursed to this life forever. An immortal cat would feel horrible because they would watch everyone they know die. Noting the use of the word 'forever', it is logical that Rock is immortal from this prespective.

Another reason why Rock could be immortal is that he is estimated to be 60 years old in human years. This would make him the oldest cat in the series, and it is worth noting that the oldest cat in the clans, Mistystar, is 16.6. That is a huge difference.
