Feline Pregnancy

A cat's pregnancy usually lasts between 58 and 65 days. They have the ability to  become pregnant  as early as six months of age and go into heat twice a year, in the spring and the fall.  Cats are induced ovulators, this means they need stimulation by a male in order for their ovaries to release eggs. Until this happens, a cat can remain quite uncomfortable throughout the heat period, which can last up to three weeks. Anyone who has a female cat knows that the sound a cat makes during heat is one of extreme distress. 

If you are planning to breed your cat, you need to make plans well in advance and have a male lined up.  Be aware that the act of mating can be pretty intense because the male will grab the female by the neck with his teeth, often resulting in some hair loss and scarring. Your vet can confirm the pregnancy after about four weeks by either palpation (feeling the abdomen with a gentle squeeze), ultrasound or a bit later on by radiograph. During the pregnancy the cat's caloric intake and weight will increase, so be sure to provide additional food. Toward the end of the pregnancy her mammary glands will swell, and she may start nesting in a specific area.
