He got killed when a branch fell on him during a storm.
Sorrelkit (Sorreltail), Rainkit (Rainwhisker), and Sootkit (Sootfur).
Leafpool became a normal warrior in ThunderClan.
Rainwhisker's father was Whitestorm and his mother was Willowpelt. His brother was Sootfur and his sister was Sorreltail. He had two half-brothers, Darkstripe and Graystripe.
Whitewing is a white she-cat with green eyes from the Warriors series. She is the daughter of Rainwhisker and Sorreltail, and the sister of Amberpaw and Dewpaw. Whitewing is a kind and loyal warrior of ThunderClan.
whitestorms kits are Sorreltail, Sootfur,and rainwhisker But that's not all! Brindleface had his first kits, Ferncloud and Ashfur, and then Willowpelt had his second (and last) litter, Sorreltail, Sootfur, and Rainwhisker. His adopted son is Cloudtail, the blood son of Firestar's sister Princess.
Rainwhisker is a fictional character from the Warriors book series by Erin Hunter. As a warrior cat, Rainwhisker doesn't have romantic love interests in the traditional human sense. His allegiances lie with his clan and his loyalty is to his fellow tribe members.
In the beginning of The Sight, it is mentioned that Rainwhisker was killed by a falling branch. Page 7, "...and Rainwhisker had been killed during a storm, struck by a falling branch." I think it is so sad for Sorreltail. Her parents (Willowpelt and Whitestorm) died when she was young, then Sootfur died in the badger attack, and then both Molepaw and Rainwhisker died in the same leaf-bare. Later on, her daughter Honeyfern died of the snake attack.
She is devastated by Tigerclaw's betrayal and even starts believeing that Starclan is against Thunderclan.

The second leader of Thunderclan was Owlstar.
Rainwhisker's mate was Sorreltail. They had a daughter named Honeyfern.
This is not likely. After all, the entire series is set in Thunderclan.
