Yes, in the latest series, they have four kits, but only two survive. Their kits are- Sparkkit, Alderkit, Juniperkit, and Dandelionkit. Juniperkit, a a male, and Dandelionkit, a female, dies. Sparkkit, a female, and Alderkit, a male, survive. In the latest book, both become apprentices.
No they don't have any kits. You may think that they did have Jaykit, Hollykit, and Lionkit but those are actually Crowfeather and Leafpool's kits. Squirrelflight covered for Leafpool and took the kits.
squrrielflight didn't have any kits. lionkit, hollykit, and jaykit, were her sister's kits.p.s. I am not telling you squrrielflight's sister's name
No, Squirrelflight is not infertile. She has had kits in the past and is able to have more kits in the future if she chooses to.
Squirrelflight was foster mother to Jayfeather, Lionblaze, and Hollyleaf, but as revealed in Sunrise, they are actually the kits of Leafpool and Crowfeather. I suppose Squirrelflight is barren because she had been mates with Brambleclaw for so long and still doesn't have kits. But since they are not mates anymore, Squirrelflight probably won't have any kits.
YES. in one of the books, Ashfur tries to kill the Three but Squirrelflight says that they aren't really her kits. Later, the Three unravel the web of mysteries and find out who their true parents are.
Brambleclaw thought the kits were his because Squirrelflight passed them off as his to protect their true parentage, which was revealed later to be Leafpool and Crowfeather's kits. Squirrelflight did this to protect her sister, Leafpool, who had broken the warrior code by falling in love with Crowfeather.
Brambleclaw has no kits biologically, since it has been revealed that Squirrelflight did not bear him kits; instead, the kits were her sister Leafpool's. However, his adopted kits (the aforementioned kits) would be Jayfeather, Lionblaze, and Hollyleaf (presumed deceased).
Sandstorm's kits are Squirrelkit (Squirrelflight), and Leafkit (Leafpool).
Squirrelflight is not infertile. She and Bramblestar have kits together in the Warrior Cats series.
Leafpool gave her kits to Squirrelflight because she thought she was doing the right thing. Medicine cats can't have kits so if she used Squirrelflight she could contiue to be a medicine cat and her kits wouldn't grow up being half-clan and looked down upon.
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.
