Chicago FAQ
Do I have to spay my pet in Chicago?
No general law requires it. Mandatory sterilization applies only after a dangerous-dog finding under MCC 7-12-051 or as a condition of adopting from Chicago Animal Care and Control under MCC 7-12-310.
Where can I get free or low-cost surgery?
PAWS Chicago Lurie Spay/Neuter Clinic, the Anti-Cruelty Society, and Animal Welfare League run subsidized programs. CACC also publishes vouchers for income-qualified residents on its city website.
Houston FAQ
Does Houston require me to spay or neuter my pet?
Not for owned pets generally. BARC and partner clinics strongly encourage sterilization, and adopted shelter animals must be altered, but Chapter 6 does not impose a citywide mandate on private owners.
Where can I get a low-cost spay or neuter?
BARC posts vouchers and mobile-clinic schedules at houstontx.gov/barc. Emancipet, SNAP, and Friends For Life run additional low-cost clinics, often free for residents in priority ZIP codes.
