It’s almost that magical time of 12 months that the Humane Society of America likens to a “natural disaster.” Kitten season.
“The level of emotions for months on end is so draining, said Ann Dunn, director of Oakland Animal Services, a city-run shelter in the San Francisco Bay Area. “And every year we just know it’s going to get harder.”
Across the United States, summer time is the peak of “kitten season,” usually outlined because the warm-weather months between spring and fall throughout which cat turns into most fertile. For over a decade, animal shelters throughout the nation have famous kitten season beginning earlier and lasting longer. Some specialists say the consequences of local weather change, comparable to milder winters and an earlier begin to spring, could responsible for the uptick in feline delivery charges.
This previous February, Dunn’s shelter held a clinic for spaying and neutering outside cats. Although kitten season in Northern California doesn’t usually kick off till May, organizers discovered that over half of the feminine cats had been already pregnant. “It’s terrifying,” Dunn stated. “It just keeps getting earlier and going later.”

Cats reproduce when females begin estrus, extra generally often known as “going into heat,” throughout which hormones and conduct modifications sign she’s able to mate. Cats can go into warmth a number of instances a 12 months, with every cycle lasting as much as two weeks. But births usually go up between the months of April and October. While it’s nicely established that lengthening daylight triggers a cat’s estrus, the impact of rising temperatures on kitten season isn’t but understood.
One principle is that milder winters could imply cats have the sources to begin mating sooner. “No animal is going to breed unless they can survive,” stated Christopher Lepczyk, an ecologist at Auburn University and outstanding researcher of free ranging cats. Outdoor cats’ meals provide may be growing, as some prey, comparable to small rodents, could have inhabitants booms in hotter climate themselves. Kittens may be extra prone to survive as winters turn out to be much less harsh. “I would argue that temperature really matters,” he stated.
Others, like Peter J. Wolf, a senior strategist on the Best Friends Animal Society, assume the rise comes all the way down to visibility reasonably than something organic. As the climate warms, Wolf stated folks could also be getting out extra and noticing kittens earlier within the 12 months than earlier than. Then they convey them into shelters, leading to rescue teams feeling like kitten season is beginning earlier.
Regardless of the precise mechanism, having a lot of feral cats round means bother for extra than simply animal shelters. Cats are apex predators who can wreak havoc on native biodiversity. Research exhibits that outside cats on islands have already induced or contributed to the extinction of an estimated 33 species. Wild cats pose an outsized menace to birds, which make up half their weight-reduction plan. On Hawaiʻi, often known as a fowl extinction capital of the world, cats are essentially the most devastating predators of wildlife. “We know that cats are an invasive, environmental threat,” stated Lepczyk who has revealed papers proposing administration insurance policies for outside cats.
Scientists, conservationists, and cat advocates all agree unchecked outside cat populations are an issue, however they continue to be deeply divided on options. While some conservationists suggest the focused killing of cats, often known as culling, cat populations have been noticed to bounce again rapidly, and a single feminine cat and her offspring can produce no less than 100 descendants, if not hundreds, in simply seven years.
Although sterilization protocols comparable to “trap, neuter, and release” are favored by many cat rescue organizations, Lepczyk stated it’s almost inconceivable to do it successfully, partly due to how freely the animals roam and the way rapidly they procreate. Without houses or sanctuaries after sterilization, returning cats exterior means they might have a low high quality of life, unfold illness, and proceed to hurt wildlife. “No matter what technique you use, if you don’t stop the flow of new cats into the landscape, it’s not gonna matter,” stated Lepczyk.
Rescue shelters, already below pressure from useful resource and veterinary shortages, are scrambling to confront their new actuality. While some launch supplies to assist the group establish when outside kittens want intervention, others deal with recruiting for foster volunteer packages, which turn out to be important caring for kittens who want around-the-clock-care.
“As the population continues to explode, how do we address all these little lives that need our help?” Dunn stated. “We’re giving this everything we have.”
