Their finances
from their own IRS Form 990, fiscal year 2025Spending breakdown — and why we do not lead with it
A high figure here is not straightforwardly good. The measure counts money spent on programmes against money spent running the organisation, so it rewards charities that under-invest in staff, systems and evaluation — and it can be moved by accounting choices rather than by doing more. The largest charity raters publicly abandoned it as a headline measure for exactly that reason. It is here because it is on the filing and people look for it, not because we think it tells you who to give to.
No comparison shown. We list only 1 charity under this cause with a filing, which is too few to rank against meaningfully. A percentile drawn from a handful of organisations looks precise and means nothing.
Figures are as the organisation reported them to the IRS. We do not adjust, score or rate them, and we do not combine them into a single number — that would require deciding how much each one matters, which is your judgement to make, not ours.
Is this your organisation? If anything here is wrong, out of date, or you would rather not be listed at all, tell us and we will correct it or remove you. We do not require a reason.

3,543 filed under IRS code B90 in 2025A percentile here is a position among charities the IRS classifies the same way — it is not a score, and being lower is not automatically worse. A large organisation running its own veterinary hospitals will spend a different share on programmes than one that passes grants through, and both are doing their job.

A dash means the organisation has not filed a full Form 990 in the years we hold, or files the short return that omits the figure. It is not a zero, and it is not a mark against them.
