HOW THE HOLIDAY CAME TO BE

A shelter push timed to the busiest month for kittens.

American Humane, the United States' first national humane organization, created Adopt-A-Cat Month in 1974 as a June campaign to push shelter adoption over buying, timed to the height of kitten season when shelters fill with new litters.

INTRO

Why a cat-adoption push lands in June, on purpose

<![CDATA[

June is not a random month for a cat-adoption campaign. It is the worst month, and that is the point.

Across the United States, kitten intakes at shelters climb sharply between April and June. In many regions during that window, most feline arrivals are newborns, kittens too young to fend for themselves. Shelter workers call it kitten season.

The wave does not even crest in June. Intake actually peaks in May, so the campaign opens just as shelters fill to their fullest.

National Adopt A Cat Month was built to meet that surge. It also shares the calendar with a separate June campaign run by a different organization, which is why two "adopt a cat" months get tangled together every summer.

ORIGINS

Adopt A Cat Month history

INTRODUCTION

The organization behind the month did not begin with cats, or even mainly with pets. American Humane organized in Cleveland, Ohio, on October 9, 1877, as the first national humane organization in the country.

Its early reach was broad. The group worked on the protection of children and working animals long before shelter cats became a national cause.

CHAPTER 01

From broad welfare work to a specific problem

By the 1970s, the organization had nearly a century of welfare work behind it. It also faced a recurring shelter problem with a clear seasonal shape: cats arriving faster than homes could take them.

That gap is what a national campaign could close. An established group with a national voice could ask the public to do one concrete thing at the right time of year.

CHAPTER 02

A campaign pegged to a calendar problem

In 1974, American Humane created Adopt-A-Cat Month and fixed it to June. The pitch was narrow on purpose: adopt a cat from a shelter rather than buy one from a store.

The choice of month did the persuading. Aiming the push at the arrival of new litters put the message in front of the public exactly when shelters most needed adopters. The organization has run it every June since.

The annual pitch has stayed personal. Opening the 2018 campaign, American Humane President and CEO Dr. Robin Ganzert pointed to the "millions of healthy, adoptable cats" in shelters waiting for their forever homes.

EVIDENCE

The numbers come from a near-census

Shelter Animals Count compiles data reported by more than 14,000 organizations, making it the closest thing the US has to a shelter census. That scale is what lets the kitten-season pattern be measured rather than assumed.

How to Celebrate National Adopt A Cat Month

ADOPT

Adopt instead of buying, per the sponsors

The whole point of the month, as American Humane frames it, is choosing a shelter or rescue cat over a store-bought one. The ASPCA runs a parallel June message urging the same choice during peak kitten season.

FOSTER

Foster a litter through kitten season

Shelters need temporary homes most in late spring and early summer, when neonatal kittens overwhelm intake. Ask your local shelter whether it runs a foster program for the season.

HELP

Help a working shelter with hands-on time

Volunteering covers the unglamorous work that keeps a shelter running during its busiest stretch. Cleaning, socializing cats, and staffing adoption events all ease the June crunch.

SHARE

Share verified adoption resources

Point friends to the sponsoring organizations rather than to rumor or resale listings. Linking the ASPCA's June cat campaign spreads accurate guidance during the season it matters most.
