Does de-sexing a female cat mean removing the uterus?

Female cats are de-sexed by removing their ovaries and uterus. Before the operation, the cat has to fast for 6 hours and abstain from water for 2 hours. After the operation it is necessary to wear an Elizabethan collar until the wound is completely healed, and to let the cat rest, pay attention to wound hygiene and give anti-inflammatory injections three days after the operation.
