Best Answer: Female cats typically have their first heat around the age of six months, which usually lasts for 5 to 7 days. Cat's heat cycles are light dependent and they usually have heat cycles every 9 to 13 days from January through October, though some indoor cats exposed to constant light times will cycle all year. I advise unless you want kittens to keep her in at these times.
But you canât tell if your cat has a fever by feeling for a warm, dry nose, as many people believe. The only way to know for sure -- with either a human or a cat -- is to take its temperature. A normal temperature in cats ranges from 100.4Âº to 102.5Âº Fahrenheit. A fever in cats occurs when temperatures rise above 102.5Âº F.
