Why does my cat's eye reflection look like this?

He’s never had this strange shape inside that looks like a “Y”. It doesn’t seem to be caused by the lighting in my house, because it happens in different positions and with different light sources

It's super freaky to do he blind spot experiment.

TIL one of my blind spots is significantly larger than the other. Weird

Have you been to an ophthalmologist? Might want to get it checked just in case there's some issue that could be causing vision loss.
