Tree House Humane Society

What Tree House Humane Society does

Tree House Humane Society is a Chicago-based 501(c)(3) nonprofit founded in 1971 that operates a portfolio of cat-focused animal welfare programs from a single state-of-the-art facility at 7225 N. Western Avenue. Its core offerings include a cageless community-housing adoption center placing roughly 1,000 cats per year, a Veterinary Wellness Center (opened 2021) serving up to 7,000 pets annually with affordable spay/neuter and wellness services, a Community Cats program managing over 4,000 outdoor cats across 1,000+ registered colonies, the Cats at Work working-cat placement program, a Cat Café featuring FeLV+ adoptable cats, foster and humane education programs, and since 2024 mobile pop-up veterinary clinics in underserved neighborhoods.

The organization operates without proprietary technology, relying on third-party platforms: Shelterluv for adoption management, Clinic HQ for veterinary scheduling, Digital Cheetah for volunteers, and Petco Love Lost for lost-pet reunification. Its revenue model is donation-led (one-time, monthly, tribute, stock, crypto, employer matching), supplemented by adoption fees ($75-$165), affordable veterinary services at tiered pricing, café revenue ($10 lounge reservations), merchandise sales, Cats at Work placement fees ($350-$420), and corporate grants/partnerships (Purina, Bissell Pet Foundation, Chewy Rescue Referral, Whisker/Litter-Robot). One of only two Chicago facilities authorized to hold stray cats, Tree House partners with Chicago Animal Care and Control and the Anti-Cruelty Society for intake diversion, and engages over 200 active volunteers alongside a staff of 11-50. Since CEO Raissa Allaire took leadership in May 2018, reserves have been quadrupled, the VWC and mobile clinic programs launched, and the organization earned Charity Navigator's Four-Star rating and Candid's 2025 Platinum Seal of Transparency.
