The cat rules changing in the City of Brimbank.

Brimbank doesn't have a cat curfew in force just yet, so cats aren't legally required to be contained today. That changes on 1 January 2028, when the council's new Cat Containment Initiative will require every cat to be kept on its owner's property at all times, with a transition period already under way to help owners get ready. Here's what we've collated on the council's cat rules, from registration to what it takes to build a cat run, with links to the council's own pages.

Coming up2028: Warning period before fines
The essentials

Cat rules in Brimbank at a glance.

The headline cat rules for this area. These are a starting point, the full detail is in the questions below, and the final word rests with the council.

Cat containment
No curfew today, but all cats must be kept on the property at all times from 1 January 2028. The transition period started in July 2026, and council plans a period of warnings after the start date before fines are issued.
Registration
Cats over 3 months must be registered with council; renew every year by 10 April.
Desexing
Brimbank has an order making desexing compulsory before a cat can be registered. Exemptions cover a written vet health exemption, members of an applicable organisation and registered breeding businesses. Microchip required too. Exempt cats pay a much higher fee.
Cats per property
Up to two cats without a permit; more than two needs an excess animal permit.
Enclosure permit
A cat run needs no animal permit. A building permit can apply if it's large or tall, so check with the council.

This information is not professional or legal advice, it's research we've collated to help you get started. Council rules change, so always check the current details with the City of Brimbank (opens in a new tab) before you build.

Does the City of Brimbank have a cat curfew or containment rules?

Not right now, so there's no curfew in force today. That's changing though: under the council's Domestic Animal Management Plan, a Cat Containment Initiative will require all cats to be kept on their owner's property at all times from 1 January 2028, and a transition period is already running to give owners time to get set up. A fully enclosed cat run is the easy way to meet this, because it keeps your cat on your property day and night without shutting it indoors.

Do I need to register my cat with the City of Brimbank?

Yes. Cats over three months old must be registered with Brimbank, and registration is renewed every year by 10 April. Fees are set each year, with a cheaper rate for desexed cats and a discount for eligible pension cardholders. Check the council's register-your-pet page for the current amounts.

Does my cat need to be desexed and microchipped?

Yes to both. Brimbank is one of a handful of Victorian councils with an order that makes desexing compulsory before a cat can be registered, and your cat must be microchipped as well. The exemptions are narrow: a letter from your vet giving health reasons for delaying or skipping it (age alone doesn't count), membership of an applicable organisation, or running a registered breeding business. Cats exempt from desexing pay a much higher registration fee. Council also runs subsidised desexing programs from time to time, so it's worth asking what's on offer.

How many cats can I keep at one property in Brimbank?

You can keep up to two cats at a property without needing a permit. To keep more than two you'll need an excess animal permit from the council, which involves an application and a fee. It's worth sorting this out before you take on any extra cats.

Do I need a council permit to build a cat enclosure in Brimbank?

The cat run itself doesn't need an animal permit. A building permit is a separate question and can be triggered by the structure's size, height or how close it sits to a boundary. As a rough guide, small, low, freestanding enclosures often don't need one, but it's best to check with Brimbank's building team before you start.

Are there height or boundary rules a catio has to meet?

There can be. Building rules around height and setback from boundaries can apply once a structure gets larger or taller, and planning overlays on some properties add extra conditions. We design our enclosures to sit comfortably within these limits, and we're happy to help you confirm the details with the council before we build.

What happens if my cat is found wandering in Brimbank?

A roaming cat can be picked up and impounded, and you'll usually pay release and daily holding fees to get it back. A registered, microchipped cat is far quicker to reunite with its owner. Once the containment rule starts in 2028, letting a cat roam off your property will also be a breach of the local rules.

Can I build a catio if I rent or live in an apartment?

Yes, but get your landlord's or owners corporation's written approval first, since you're adding or attaching a structure. For rentals we can build freestanding or easily removable enclosures, and for balconies or windows there are neat options that don't need permanent fixings. Just check what your lease or body corporate allows before we start.

How does a catio help me follow Brimbank's cat rules?

A fully enclosed catio keeps your cat safely on your property, which is exactly what containment rules ask for, while still giving them fresh air and the sounds and smells of outside. We build a range of escape-proof enclosures, from a discreet patio catio to a side run or netting over the whole backyard, so there's an option to suit your home. Build a quote to get started.
