What Oklahoma Humane Society does
Mission
The primary goal of the Oklahoma Humane Society is to end the needless euthanasia of adoptable pets in oklahoma. Through its partnership with the oklahoma city animal shelter, the organization is able to transfer dogs and cats at risk of euthanasia into its adoption and relocation programs. Through its spay and neuter program, the organization prevents the birth of unwanted pets and helps reduce intake at the oklahoma city animal shelter. Humane education programs promote compassion toward animals and teach responsible pet ownership. The organization has a statewide initiative that is targeting rural communities to reduce pet overpopulation through spay / neuter, vaccines and education.
As stated on its FY2024 Form 990.

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 2023 to 2024, from $4.1M to $20M (+372%).
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: 2020 5% · 2021 8% · 2024 0%. Grants only. Government contracts and fees sit inside program revenue.
90% of OKLAHOMA HUMANE SOCIETY’s revenue is contributions — more reliant on donations than three-quarters of its peers (67% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 8 reported years ran a deficit.

Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.

Who funds it, year by year
2017 → 2023: the base broadened from 10 funders to 31 funders, grant income rose $234k → $402k.
10 of 61 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 13% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
Left out of every figure on this page: $1.6M from 2 payers (the payer shares this organization's board, largest Oklahoma City Community Foundation Inc). These are real filings, and they are not money OKLAHOMA HUMANE SOCIETY raised.
From the IRS filings of OKLAHOMA HUMANE SOCIETY’s funders (the co-funder graph). Top 30 of 61 funders by total. Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
OKLAHOMA HUMANE SOCIETY has a broad base — no single funder exceeds 14% of grant income, and it takes 4 funders to reach half.
the vertical line marks half of all grant income — 4 funders to its left
33% 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 OKLAHOMA HUMANE SOCIETY.
Largest funder’s share by year: 2017 38% · 2018 39% · 2019 45% · 2020 64% · 2021 27% · 2022 43% · 2023 25% — diversifying over time.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How long its funders stay
45% of OKLAHOMA HUMANE SOCIETY's funders are still giving 3 years after their first grant; 64% give in more than one year at all.
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. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
68% of OKLAHOMA HUMANE SOCIETY's grant income comes from Oklahoma funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $543k arriving through sponsors registered in 9 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. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
