What Tree House Humane Society Inc does
Mission
To empower communities of caregivers to advocate and care for cats - while reimagining solutions for a more compassionate future.
As stated on its FY2025 Form 990.
Programs
Clinical and veterinary services: high-quality vet care, spay/neuter, vaccinations, and surgeries for resident and community cats; and foster care for cats who are recovering. The society opened its veterinary wellness center during 2021 to serve the general public. Pet caregivers are able to access low cost spay/neuter and basic wellness services that will help them keep their pets healthy. This community initiative, which serves up to 6,000 pets each year, aims to fight one of the causes of pets being surrendered to shelters: illness and inability to pay for treatment.

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 2024 to 2025, from $11M to $14M (+23%).
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 15% · 2021 9%. Grants only. Government contracts and fees sit inside program revenue.
84% of TREE HOUSE HUMANE SOCIETY INC’s revenue is contributions — more donation-reliant than the typical peer (74% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 9 reported years ran a deficit.

From the IRS filings of TREE HOUSE HUMANE SOCIETY INC’s funders (the co-funder graph). Top 30 of 71 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
TREE HOUSE HUMANE SOCIETY INC has a broad base — no single funder exceeds 22% of grant income, and it takes 5 funders to reach half.
the vertical line marks half of all grant income — 5 funders to its left
53% 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 TREE HOUSE HUMANE SOCIETY INC.
Largest funder’s share by year: 2017 32% · 2018 24% · 2019 33% · 2020 23% · 2021 52% · 2022 29% · 2023 24% — 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.

45% of TREE HOUSE HUMANE SOCIETY INC's funders are still giving 3 years after their first grant; 59% 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
55% of TREE HOUSE HUMANE SOCIETY INC's grant income comes from Illinois funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $994k arriving through sponsors registered in 11 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.
