Male or female

I recently rescued a cat and I am unsure about the gender. Could someone please tell me if my cat is male or female

Hello!  You can actually do this for yourself.  If you look for two holes in your cats perinneum, one - the anus - directly below the tail and another lower down.   In a female, the lower one is a slit, not a round hole, and starts almost immediately after the hole for the anus finishes - there is no (or maybe a negligible cm of) hairy fur in between.  In a male, there is a gap between the anus and the second hole, which in a male is round and represents the end of the penis.  Sometimes one finds testicles or just the ghost of where the testicles once were / are going to appear, in the gap between the anus and the end of the penis.  I'm not allowed to sex animals for you online but I hope that that helps!
