The cat rules that matter most here, in short. Treat them as a starting point, check the questions below for detail, and confirm anything important with the council.
- Cat containment
- Cats must be kept on your property at all times under the Casey Community Local Law 2025 and the Domestic Animals Act 1994. Cats can't be kept at all in some estates near the Royal Botanic Gardens Cranbourne.
- Registration
- Register cats with the council from 3 months old, then renew each year by 10 April. Fees are set yearly.
- Desexing
- Cats must be microchipped and desexed before Casey will register them, unless a vet grants an exemption. Desexed cats and concession holders pay less.
- Cats per property
- Up to two cats without an excess animal permit, whatever the size of your block. More than that needs a permit.
- Enclosure permit
- No animal permit for a cat run itself. A building or planning permit can apply by size, height, setback or overlay, so check with the council.

Does the City of Casey have a cat curfew or containment rules?
Casey doesn't run a night-only curfew, it's a full-time containment rule. Under the Casey Community Local Law and the Domestic Animals Act 1994 your cat has to be kept on your property at all times, and you can be fined if it's found off your land. There are also a few estates near the Royal Botanic Gardens Cranbourne, including Botanic Ridge and Settlers Run, where cats can't be kept at all. A fully enclosed cat run is one of the easiest ways to meet the rule, since it lets your cat enjoy the outdoors while staying safely on your property.
Do I need to register my cat with the City of Casey?
Yes. Cats in Casey must be registered with the council from three months of age, and registration runs on a yearly cycle that renews on 10 April. The council sends a reminder a few weeks before it falls due. Fees are set each year, and desexed cats and concession card holders pay a reduced rate, so check the council's registration page for the current amounts.
Does my cat need to be desexed and microchipped?
In Casey your cat needs to be microchipped and desexed before the council will register it, unless a vet has granted a medical exemption. The council has required desexing for cat registration since 2007, and microchipping is a state requirement under the Domestic Animals Act 1994. A microchip also makes it far more likely you'll be reunited with your cat if it ever gets out, which is another good reason a secure enclosure helps.
How many cats can I keep at one property in Casey?
You can keep up to two cats at a property in Casey without needing a permit, and this applies no matter how big your block is. If you want to keep more, you'll need to apply for an excess animal permit, which involves a property inspection and an annual renewal by 10 April. It's worth checking the council's excess animal permit page before you take on extra cats.
Do I need a council permit to build a cat enclosure in Casey?
The cat run itself doesn't need an animal permit. What can come into play is a building or planning permit, which in Victoria is usually triggered by the size, height or position of the structure rather than the fact that it's for a cat. As a general guide a small enclosure often sits under the building-permit threshold, but boundary setbacks and planning overlays can change that, so it's best to confirm with Casey's building or planning team before you start.
Are there height or boundary rules a catio has to meet?
There can be. As a general guide in Victoria, a freestanding, lightweight structure will often avoid needing a building permit if it stays under about 10 square metres in floor area and no more than 3 metres high, but that's a state guide rather than a Casey-specific number. Setbacks from your boundaries and any planning overlays on your block still apply. We design our cat enclosures to sit within those kinds of limits where we can, and if your site needs anything unusual it's worth a quick check with the council first.
What happens if my cat is found wandering in Casey?
If your cat is found off your property you can be fined, and the council may seize a cat that's at large. A registered, microchipped cat is much easier for the council to return to you, while an unregistered one is harder to trace and can mean release and holding fees. Keeping your cat contained, ideally in a secure enclosure, is the simplest way to avoid the whole situation.
Can I build a catio if I rent or live in an apartment?
You can, though if you're renting you'll want your landlord's written permission first, and we can design freestanding or easily removable enclosures that don't damage the property. For units or apartments, a balcony or courtyard enclosure works well and still keeps your cat safely contained as Casey's rules require. It's also worth a look at any owners corporation rules before you commit.
How does a catio help me follow Casey'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.
