Cloudtail doesn't believe in starclan at first but he eventually does at some point in the books I believe.
Longtail believes in starclan, cloudtail is the one that doesn't. i don't think purdy does either.
In reality, no. But in the warrior book series, yes. Most clan cats do believe in StarClan, with the exception of a few cats, generally those born outside the Clan like Mothwing and Cloudtail.
If the cats are good even if they don't believe in StarClan they go to StarClan, but the cats like the cats from BloodClan don't. I'm not sure about the cats that have never heard of StarClan, but are good. Even if some cats believe in StarClan, but they do some really bad things, then they go to the "Place of No Stars".
As to that no one knows. But I do not think they will because of the oncoming battle between the dark forest and Starclan. And there is a rumor that Firestar is going to die. So Cloudtail may be in grief to much to worry about kits. but maybe if Erin Hunter writes another series they will.
He becomes a warrior after the battle over sunningrocks in a dangerous path. Bluestar at the time had doubt in StarClan and when she sees that Cloudtail doesn't believe in them she makes him a warrior but not any other apprentice.
He died from greencough. He was never truly excepted by StarClan so he didnt get 9 lives.
Yes, he does because Jaypaw and the others and StarClan cats Runningnose and Raggedstar make him believe in StarClan, keep reading!
that he doesn't believe in the starclan
Spiderleg and Cinderheart were Cloudtail's apprentices.
I believe that sometime, yes they will. If not when they are alive, in StarClan. Cats always realize their mistakes in StarClan.
Brightheart. When Daisy and her kits settle in, Cloudtail spent a lot of time with her, and there is a hint that they were in love. But of course, Brightheart is still Cloudtail's true love.
if cloudtail was cloudstar's warrior name then yes.
