Animal adoption often turns on a few practical factors. In the U.S., 26% of pets adopted from shelters were a first pet, and 78% of adopters reported feeling prepared after adoption counseling. Shelter operations matter too, with behavior enrichment cutting time to adoption by 18% for dogs and frequent adoption events raising adoption rates by 1.2x.
