Companion animal fostering provides temporary homes for animals awaiting adoption, significantly improving welfare outcomes compared to shelter housing, particularly for puppies, kittens, and animals with behavioral needs.
Animal fostering is among the most direct welfare interventions available to individuals without professional training or animal care facilities. Foster carers provide the individualized attention, home environment, and behavioral observation that shelters cannot replicate at scale. The welfare benefit is most acute for neonatal animals — bottle-fed kittens and pups that would not survive shelter environments — and for animals with behavioral challenges that worsen in kennel settings. Foster programs are typically low-cost to shelters while providing high welfare value for individual animals.
