Leafpool and Crowfeather had kits between the second and third series.
Squirrelflight did not have any kits of her own. She raised Leafpool's kits, Jayfeather, Lionblaze, and Hollyleaf, as her own to protect her sister's secret that she had broken the warrior code by having a litter of kits.
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 hides her secret by confiding in Squirrelflight, who agrees to raise the kits as her own. Leafpool distances herself from her kits, Jayfeather, Lionblaze, and Hollyleaf, and the clan is led to believe they are Squirrelflight's. Only a select few, including Cinderpelt, her sister, know the truth.
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.
