How does no cat notice jayfeather, hollyleaf, and lionblaze look nothing like sqirrelflight of 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 door Sandstorm of 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 vacht, bont D:

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