If there is a male cat nearby that is intact and not able to get to her physically, the heat can last longer. Estrus lasts from 4-6 days if she mates, and up to 10 days if she doesn't. It can reoccur about every two weeks.
They will keep going into heat until they die! So, you could have a 15 year old cat going into heat and getting pregnant! They go into heat until they die. My grandmother had a cat that was 20 and she went in to heat that year too. Yes, if they are not fixed, they stay in heat FOREVER, ie the rest of their lives -- 2 weeks on, 2 weeks off. Get your cat fixed. I have one that's at least 12 years old and still has kittens twice a year.
