Cook County Code Chapter 30 and the Illinois Animal Control Act require rabies vaccination for cats over four months. CCDARC offers cat licenses and TNR support for community colonies; outdoor cats remain owners' responsibility for nuisance and wildlife harm.
Under Cook County Code Chapter 30 and the Illinois Animal Control Act (510 ILCS 5), cats over four months kept in unincorporated Cook County must carry a current rabies vaccination tag. Cook County Department of Animal and Rabies Control (CCDARC) issues cat licenses tied to vaccination records and supports trap-neuter-return work for managed feral colonies through partner shelters. There is no countywide leash rule for cats, but owners remain liable for nuisance, property damage, and predation on protected wildlife. Many suburbs add their own indoor-only or licensing rules layered atop the county baseline.
Citations issue for unvaccinated cats over four months, abandonment, or chronic nuisance feeding. Fines begin near seventy-five dollars and escalate; repeat offenders face impoundment fees, abatement orders, and possible misdemeanor referrals under 510 ILCS 5.
