What Mainely Rat Rescue does
Mission
Mainely Rat Rescue's mission is to rehabilitate and find homes for surrendered or abandoned domestic rats, as well as to spread awareness, provide education, and furnish support for all the animals in its care. Other "pocket pets" such as guinea pigs, hamsters, gerbils, and mice are occasionally accepted into the program.
As stated on its FY2025 Form 990-EZ.
Program
Mainely Rat Rescue accepted into the program 561 small animals in 2025, with 480 adoptions to new homes completed. A large percentage of these animals were neutered or spayed while in the care of the rescue, as well as many having other medical and behavior issues addressed. We have again used our "Angel Fund" so that we are able to assist animals in need of medical care, while allowing them to stay with their owners.

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 $37k to $22k (−40%).
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.
98% of MAINELY RAT RESCUE’s revenue is contributions — about as donation-reliant as the typical peer (100% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 4 of the last 7 reported years ran a deficit.
Who funds it, year by year
2017 → 2023: the base broadened from 1 funder to 2 funders, grant income fell $15k → $1k.
1 of 3 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 24% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of MAINELY RAT RESCUE’s funders (the co-funder graph). 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
MAINELY RAT RESCUE leans on a few funders — its largest provides 68% of grant income and the top three 100%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
93% 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 MAINELY RAT RESCUE.
Largest funder’s share by year: 2017 100% · 2019 100% · 2020 100% · 2021 100% · 2022 95% · 2023 83% — 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.
Where its funders are
MAINELY RAT RESCUE draws 100% of its grant income from funders outside Maine, across 2 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $5k arriving through sponsors registered in 1 state 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.
