What The Humane Society for Seattleking County does
Mission
Seattle humane promotes the human-animal bond by saving and serving pets in need, regardless of age, ability, circumstance or geography.
As stated on its FY2025 Form 990.
Programs
The largest program is our shelter care and adoption services. Seattle humane is a managed-intake shelter that cares for pets, including those with treatable medical and/or behavioral issues, and there are no limits for space or time. Adoptable companion animals are provided to the public for a fee. Shelter care includes intake, transfers, adoptions, behavior support and foster program. In 2024, the lifesaver rescue transfer program accounted for more than 71% of seattle humane's animal population from 90+ high-need shelters in washington and across the country. The remaining 29% of animals came to the shelter through local surrenders. For the year ended march 31, 2025, the save rate was 98%.

$3,989,930 spent$1,204,229 earned by the program37% of program spendingFrom april 2024 through march 2025, community outreach offered through seattle humane's pet resource center included a variety of programs aimed at helping people care for their pets and reducing pet surrender by providing alternatives for pet owners. The pet food bank collected and distributed more than 58,000 meals each month to pets in the community, and we saw that need continue to grow during the year. Seattle humane distributed resources to partner shelters, food banks, senior centers, and directly to homebound pet owners in need throughout king county. Staff in the pet resource center worked with families to offer financial assistance and other resources through the pet owner assistance fund, polly's pocket fund, the spot (temporary foster) program, and pets for life program. (continued in schedule o) in addition, seattle humane offered youth education through various youth programs, including the humane teen club and adventure camp for kids in the summer.

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.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2022 to 2023, from $53M to $47M (−12%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2022 6%. Grants only. Government contracts and fees sit inside program revenue.
79% of THE HUMANE SOCIETY FOR SEATTLEKING COUNTY’s revenue is contributions — more donation-reliant than the typical peer (67% for the typical peer).

the vertical line marks half of all grant income — 3 funders to its left
68% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund THE HUMANE SOCIETY FOR SEATTLEKING COUNTY.
Largest funder’s share by year: 2017 13% · 2018 18% · 2019 23% · 2020 46% · 2021 42% · 2022 34% · 2023 34% — growing more concentrated.

Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year.

Where its funders are
57% of THE HUMANE SOCIETY FOR SEATTLEKING COUNTY's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $11M arriving through sponsors registered in 16 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been.
