$927,008 spent$106,299 earned by the program25% of program spendingADOPTION The primary purpose of Berkeley Humane is to shelter homeless companionanimals until they are placed in suitable homes. In the 1970s, the Board of Directors committed to a revolutionary adoption guarantee model: that no healthy or treatable shelter animals in the Society's care would be euthanized. This commitment set the stage for Berkeley Humane placing 100% of healthy and treatable animals into loving homes for nearly forty years, a commitment that awarded Berkeley Humane and partner organizations the prestigious Maddies Fund Lifesaving Award in 2009. Berkeley Humane serves the animals and people of Berkeley and the East Bay with vital services that last year alone matched over 1,000 animals with loving families and individuals.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.

Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2024 to 2025, from $11M to $14M (+31%).
