It was summer, so most cats got fat, and she had kits outside the camp, plus she used parsley to stop her milk from coming. The story was that Squirrelflight didn't notice how close to kitting she was, went off on patrol, and Leafpool was collecting herbs and found her there.
She didn't. Some cats noticed that Leafpool was beginning to get a larger belly, but because she was a medicine cat they never suspected that she was about to have kits.
Leafpool and Crowfeather had kits between the second and third series.
No because the kits are Crowfeather's and Leafpool's and Ashfur never fell for Leafpool
Spoiler Alert!!!Leafpool has kits with Crowfeather of WindClan. Her kits are named Hollykit(Hollyleaf), Lionkit (Lionblaze), and Jaykit (Jayfeather)
Leafpool had 3 kits; Hollykit(leaf), Lionkit(blaze), and Jaykit(feather)
Leafpool and Squirrelflight went out of camp together and found a save place for Leafpool to have her kits. They had to wait until the kits were strong enough to travel back toward the clan and because no other cat then Squirrelflight was with Leafpool when she kitted, it was easy for Leafpool to say that the kits were Squirrelflight's. There were some questions of course about it, but the clan believed them.
yes
before The Sight
I believe it was Sunset. Also, in the short story After Sunset: We Need To Talk Leafpool tries to tell Crowfeather she had kits but he refused to listen.
Squirrilflight and Leafpool,and leafpool will have Hollykit, Lionkit, and Jaykit and leafpool gives her kits to squirrellflight.
Sandstorm's kits are Squirrelkit (Squirrelflight), and Leafkit (Leafpool).
Leafpool has kits with Crowfeather in the book "Sunset," part of the Warriors series by Erin Hunter. The kits are named Jaykit, Hollykit, and Lionkit.
