Am I allowed to have an outdoor cat in Denmark?
Yes — a cat may roam free, and there is no leash law as for dogs. ID-marking and registration of cats is voluntary in Denmark in 2026 — cats are not under the same mandatory chip regime as dogs. An EU framework on traceability has been agreed with a phase-in of up to 15 years for private cat owners, but there is still no adopted Danish cat law and no fixed Danish start date. From February 2025 the two cat registers were merged into one, but registration is still voluntary. If you choose to mark the cat, it is done with a chip or ear tattoo by a vet. You are always responsible for the cat's welfare.
