Denver FAQ
Does my indoor-only Denver cat need a license?
Yes. DRMC chapter 8 requires every cat over six months to be licensed and rabies-vaccinated regardless of whether they go outside. Indoor cats can still escape and bites trigger reporting.
Can I feed feral cats in my Denver alley?
Only through a sanctioned TNR program. Otherwise feeding may be a public nuisance under DRMC chapter 8 and trigger wildlife-feeding rules. Coordinate with Denver Animal Protection or approved colony caretaker groups.
Phoenix FAQ
Do I need to license my cat in Phoenix?
No. Phoenix and Maricopa County only license dogs. Cats still need a current rabies vaccination after three months of age, and the certificate should be kept handy in case of bites or impound.
Can my cat roam outside?
Yes, Phoenix has no cat leash law, but you are responsible for nuisance, damage, or wildlife harm. Coyotes and birds of prey are common, so many owners choose catios or supervised outdoor time.
