June of each year is American's Humane's Adopt-A-Cat Month to promote cat adoptions from shelters. According to The Berlin Longevity Institute, cats can add as much as 10 years to their owners’ lives. Picking up a cat has a nearly instantaneous calming effect on humans, causing blood pressure to drop and the heart rate to slow. The estimated population of homeless cats in the United States (70 million) is almost equal to the number of owned cats (75 million). Throughout the spring and summer, animal shelters throughout the country are inundated with dozens of litters of kittens. Tragically, about 71% of these animals will have to be put to sleep because there are not enough loving homes. This is why American Humane's Adopt-A-Cat Month was established. Celebrated every June, the tradition promotes cat adoptions from shelters and provides an opportunity to teach the public how to care for their pets responsibly.
