How does no cat notice jayfeather, hollyleaf, and lionblaze look nothing like sqirrelflight or brambleclaw?

Jayfeather is a dark gray almost black like Crowfeather. His eyes are blue too. Hollyleaf is black like Crowfeather also.
Lionblaze almost looks like Squirrelflight but not exactly. Mabey he got it by Sandstorm or Firestar. The clan dosnt think about it. They believe when a queen tells the clan it's her kit(s) they believe it.

The clan didn't notice our fur D:

Doesn't Lionblaze look like his mother Leafpool? She's Squirrelflight's sister, so nobody would think twice about who Lionblaze looks like.
