Mouseriver

Mouseriver is a small, sleek gray tom with dark gray and silver patches across his body; he has soft green eyes.

As of now, he has no speaking role in the books.

The Dark Hope
He is rescued from the river along the StoneClan border, alongside his littermates, by Stonesplash. Thistlefoot assumes that they are StoneClan-blooded, but Brookstar insists that they take them back to the camp. While not disclosed, he is either carried back to camp by Thistlefoot or Stonesplash.

He is later seen nursing at Jadeclaw's belly, having been named Mousekit by the queens, alongside his littermates Featherkit and Darkkit.

Featherkit later mentions him, stating that he never plays fair.

It is noted that while Blackrose is trying to be motherly to Bramblekit and Stormkit, but it, like raising Mousekit, Featherkit and Darkkit, is difficult.

It is noted that Ravenwing stayed behind in the nursery when Duskpaw is apprenticed to help the queens with all of the kits. She is seen looking after Mousekit and his littermates, the three being noted as almost being six moons old and ready to be apprenticed.

He is apprenticed and becomes Mousepaw alongside Featherpaw and Darkpaw, with his mentor being Kindlestrike.

The Sun Path
He is named Mouseriver, alongside his littermates who are named Feathermist and Darkfall respectively.

A Dangerous Omen
He is assigned by Owlfoot to Jadeclaw's hunting party. The other cats in the party are Sparrowflight, Blackrose, and Darkfall.

He is later assigned by Ravenwing to the southern search patrol when Cinderfall's kits go missing. He is led by Junipertail, and accompanied by Rockstep, Kindlestrike and Goldenhawk.
