About this problem
"A righteous man cares for the needs of his animal." Proverbs 12:10, NIV
Animal shelters perform essential work. In 2024, approximately 5.8 million dogs and cats entered US shelters, and around 4.2 million found adoptive homes. About 607,000 were euthanised, down dramatically from an estimated 2.6 million as recently as 2011. Shelters reunite lost pets with families, provide veterinary care, protect communities from stray animals, and give abandoned animals a second chance.
Many Christians feel a deep pull to support animal shelters, whether through donations, volunteering, or fostering. This instinct is good: the Bible affirms that caring for animals is part of righteous living (Proverbs 12:10), and the suffering of abandoned and mistreated companion animals is real and deserving of compassion.
However, when we evaluate animal shelters through the ITN framework CFI uses, animal shelters are among the least neglected causes in the animal welfare space: roughly 95% of all US charitable donations to animal causes go to companion animal organisations. Meanwhile, the animals who suffer the most, the estimated 83 billion land animals and over 100 billion fish killed for food each year globally, receive a tiny fraction of that funding. For every single dog or cat euthanised in a US shelter, more than 14,000 farmed animals are slaughtered.
This does not mean animal shelters are unimportant. It means that Christians seeking to reduce the most animal suffering with their time and money should seriously consider whether their resources could go further elsewhere.

Our overall view
Rarely Recommended
We do not recommend animal shelters as a priority cause area for Christians seeking to maximise their impact on animal welfare. Animal shelters are important community institutions, but they are already well-funded relative to other animal welfare causes, and the cost per animal helped is orders of magnitude higher than for the most effective farm animal welfare organisations.
What is our recommendation based on?
Biblical themes:
Scripture affirms human responsibility for animal welfare. Proverbs 12:10 teaches that caring for animals is a mark of righteousness. God's covenant after the flood encompasses "every living creature" (Genesis 9:10).
The creation mandate (Genesis 1:26–28) gives humans dominion over animals, which we understand to include stewardship and not as a license for exploitation. This responsibility extends to all animals, not only companion animals.
There is no biblical basis for valuing the suffering of a dog or cat more highly than the suffering of a chicken, pig, or fish. If anything, the Bible's references to animal care overwhelmingly concern livestock and working animals rather than pets.
Christians Past and Present:
Christians have a long tradition of concern for animal welfare. John Wesley was an early advocate for the humane treatment of animals. William Wilberforce, famous for his campaign to end the slave trade, was also a co-founder of the Royal Society for the Prevention of Cruelty to Animals, the first animal welfare charity.
Many churches today run or support local animal rescue efforts as a form of community service and compassion ministry.
However, the Christian tradition of animal stewardship arguably applies most urgently where suffering is greatest, and the evidence strongly suggests that factory farming, not companion animal homelessness, is where animal suffering is most concentrated.
The cost-effectiveness gap:
Animal shelters cost hundreds to thousands of dollars/pounds per animal helped. Battersea Dogs and Cats Home in the UK, one of the oldest and best-known shelters, spends roughly £46,000 per day to care for around 7,000 animals per year, about £2,400 (about $3,200) per animal. One US shelter calculated their average cost of care at $503 per animal a decade ago, and costs have risen since. The actual cost of preparing an animal for adoption typically ranges from $200–$1,000 depending on medical needs, length of stay, and required behaviour support.
The most effective farm animal welfare organisations help animals for a fraction of this. The Humane League can spare a chicken from a life in a battery cage for approximately $0.50 through corporate welfare campaigns. This means that the $3,200 it can cost a shelter to care for one animal could instead spare over 6,000 chickens from confinement. Or help secure crate-free housing for sows and reduce painful mutilations for very large numbers of piglets. Animal Charity Evaluators’ 2025 review estimates that Sinergia Animal’s pig welfare work affects about 21 sows and 285 piglets per dollar, though with substantial uncertainty.
The scale disparity is enormous. In the US alone, about 607,000 shelter animals were euthanised in 2024. In that same period, approximately 10 billion land animals were slaughtered for food, the vast majority raised in factory farm conditions involving severe confinement, physical mutilation without anaesthesia, and denial of natural behaviours. The number of animals affected is larger by a factor of roughly 10,000 to 1.
The funding is inverted. About 95% of US animal charity donations go to companion animal organisations. Only about 3% goes specifically to farm animal welfare. According to data from Animal Charity Evaluators, Roughly $400 is donated for every animal that enters a shelter in the US, whereas for every land animal slaughtered, it is under ¢1. This makes farm animal welfare one of the most neglected cause areas relative to the scale of suffering involved.
Important caveats: The cost-effectiveness estimates for farm animal welfare organisations are less certain than those for, say, GiveWell's global health recommendations. Corporate campaign commitments do not always translate into full implementation, and it is difficult to measure the precise welfare improvement for an individual animal. The $0.85 per chicken figure is a rough estimate with significant uncertainty. Nevertheless, even if the true figure were ten or a hundred times higher, farm animal welfare would still be dramatically more cost-effective than shelter donations.
What are common theological arguments against redirecting resources?
“We have a special relationship with companion animals.” Many Christians feel a unique bond with dogs and cats. This is understandable, but the question for someone trying to maximise their impact is whether that emotional bond should determine how they allocate resources when the suffering of other animals is orders of magnitude greater.
“Shelters serve my local community.” Animal shelters do provide important local services, including public safety (stray animal control), community health, and reuniting lost pets. These are legitimate public goods. But if your goal is to reduce animal suffering, the marginal donation to a shelter is likely far less impactful than the marginal donation to an effective farm animal welfare organisation.
“I'm not sure farm animals really suffer.” There is now strong scientific evidence that chickens, pigs, cows, and fish are sentient and capable of experiencing pain, fear, and distress. Numerous peer-reviewed studies document this, and most animal welfare scientists consider it well-established for pigs, cows, and chickens, with the evidence for fish sentience increasingly accepted though still debated by some researchers. If animals' capacity for suffering is relevant to our moral obligations (and the Bible suggests it is), then the sheer volume of suffering in intense animal agriculture demands attention. In addition, pigs and cows are also similar to dogs and cats as social animals and in terms of intelligence, so if you think dogs and cats can suffer, then cows and pigs very likely can as well.
“I care about all animals, but I want to help the ones I can see.” This is a common and human response, and there is nothing wrong with volunteering at a local shelter as an act of personal compassion. But if you also want your donations to do as much good as possible for animals, the evidence points strongly toward farm animal welfare organisations.
Top ways to make an impact on animal welfare
Give to effective farm animal welfare organisations. Animal Charity Evaluators evaluates charities for cost-effectiveness. Their current top recommendations include The Humane League,Sinergia Animal, and several others focused on corporate campaigns, legal advocacy, and research.
Support alternative protein development. Organisations working on plant-based and cultivated meat alternatives address the root cause of factory farming by reducing demand for animal products. The Good Food Institute is a leading organisation in this space.
Use your career for animal welfare through policy, research, law, or food technology. See our animal cruelty report for specific career paths.
If you feel called to shelter work, consider how to make that work as impactful as possible: focus on systemic changes like trap-neuter-return programmes, community-based spay/neuter initiatives, and pet retention support, which address the root causes of shelter intake rather than managing animals after they arrive. You could also combine shelter work with advocacy for wider animal welfare issues, more animal-friendly diets, etc.
Volunteer at shelters if it brings you joy and keeps you engaged with animal welfare. Personal compassion and systemic impact are not mutually exclusive. But consider directing the bulk of your financial giving toward the organisations that help the most animals per pound or dollar if you want to help as many animals as you can.
