Timing: (affects how long you may have to hold on to the cats before placement)
Kittens: Understand that kittens are born in cycles, hence the term "kitten season." The first two waves of kittens have reached the adoptable age of 8 weeks or older by mid-summer. A lull in adoptions coincides with this pattern of over-population due to vacations and warm-weather activities mid-summer. Be open and willing to keep mid-summer kittens until October or November, after the last wave of 8-week old kittens are adopted.
Adult cats: place best between January and May, the off season for kittens.
Heat cycles: Female cats go into heat thought out the year here in Southern California. Do to weather factors, most cats will go into heat in January or February of each year. Heat cycles in the female cats are regulated by the weather. The weather affects cats at the same time, creating a surge in pregnant cats at the same time. Female cats can, and often do, become pregnant while still nursing a litter of kittens. Most cats go into heat three times a year, and with some weather patterns in Southern California, four times per year. A cat, unlike a dog, will keep repeating a heat cycle until she gets pregnant. Dogs go into heat twice a year, whether or not they get pregnant.
Kitten Seasons & Pregnancy: Pregnancy is 8-1/2 weeks from conception and kittens are up for adoption at 8 weeks of age. There are usually three seasons per year of 8 week old kittens: April/May, July/August, and October/November.
Weather: In addition to affecting the heat cycles on a female cat, a change of weather pattern can stop a mating season instantly. Weather also affects kittens under 4 weeks of age. Cold, wet weather can kill kittens under 4 weeks of age.
