THE CAT




REPRODUCTION





  • The cat is unisexual. There are male and female cats.


  • The male cat mates with the female.


  • Internal fertilisation takes place.


  • The fertilised egg grows and becomes the embryo.


  • The embryo grows in the body of the female.


  • The embryo obtains food from the blood-stream of the female.


  • The embryo develops into a tiny kitten. The kitten is born alvive after 63 days.


  • The kitten sucks milk from its mother. Thus we say that it is suckled by its mother.
