What Great Lakes Rabbit Sanctuary Inc does
Mission
Providing a safe haven to abandoned, abused and neglected domestic rabbits and others.
As stated on its FY2025 Form 990.
Programs
Great Lakes Rabbit Sanctuary provides a safe haven to abandoned, abused, and neglected domestic rabbits with the goal of adopting them out to loving homes. Those rabbits who are not eligible for adoption, due to either health or temperament, live out their lives peacefully at the sanctuary. We also strive to educate the public regarding the joys of having a house rabbit, rabbit behavior and health, as well as the importance of proper diet and care.

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 2021 to 2022, from $272k to $218k (−20%).
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: 2017 0% · 2018 0% · 2020 0% · 2021 5% · 2022 0% · 2023 17% · 2024 0% · 2025 0%. Grants only. Government contracts and fees sit inside program revenue.
95% of GREAT LAKES RABBIT SANCTUARY INC’s revenue is contributions — more donation-reliant than the typical peer (86% for the typical peer).

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.

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
99% of GREAT LAKES RABBIT SANCTUARY INC's grant income comes from Michigan funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $27k arriving through sponsors registered in 3 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.
