Reproduction - Sexing a Cat or Kittens

It can be difficult to tell the difference in male and female kittens. They are sometimes described as the male looking like a : (colon) and the female looking like an upside down exclamation mark.

Usually there is a bigger space between the anus and genital area in a male kitten - the space where the testicles will grow. It may be possible to feel small testicles in male kittens.
