How long is it from the time...

Cats generally have pregnancies lasting 58 to 65 days. They can become pregnant at 6 months of age, and they go into heat twice a year, in the spring and fall. Cats are “induced ovulators,” which means that they need stimulation by a male to release eggs from their ovaries. Until this happens, a cat may be quite uncomfortable during the heat period, which can last up to 3 weeks. For comparison purposes, elephants have a gestation period of 600 days (almost 2 years), while rabbits produce offspring in just 1 month.
