Protecting Outdoor Rabbits from Predators

Every year, thousands of outdoor pet rabbits are killed by predators. But many thousands more die without a single physical mark on them — killed by cardiac arrest induced by the terror of a predator encounter at close range. A rabbit that sees a fox pressing against the wire of its run may die of shock that night, even if the fox never gets inside.

Understanding this helps recalibrate what “predator protection” means. It’s not only about preventing physical access — it’s also about preventing predators from reaching the enclosure at all.

The Predators

Foxes

The primary outdoor rabbit predator in UK and much of Europe. Foxes are:

• Strong enough to bend standard chicken wire
• Capable of lifting unsecured hutch lids with their noses
• Expert diggers — will excavate under a run given time and motivation
• Active primarily at dusk, night, and dawn — the times rabbits are most active

Dogs

Domestic dogs, straying dogs, and wild dogs. A dog that cannot break in will still terrify rabbits severely through the wire. Ensure your garden boundaries are dog-secure as a first line of defence.

Cats

Domestic and feral cats are unlikely to kill adult rabbits but will terrify them. Cats regularly walk through gardens at night. The sight, sound, or smell of a cat through wire causes significant stress. Some cats will attempt to reach through wire to scratch.

Birds of Prey

Buzzards, red kites, sparrowhawks, and owls can take small rabbits — and will terrify larger ones even without physical contact. Overhead cover is essential for any exposed run.

Rats and Stoats

Rats can enter through gaps of approximately 1.5cm. Stoats can pass through a 2.5cm gap. They will kill and eat small or young rabbits, and can enter a standard hutch through ventilation gaps if these are not properly protected with small-gauge mesh.

Mink

In areas near waterways, mink are a significant threat. They are similar in ability and size to stoats.

What Secure Actually Means

Standard chicken wire (hexagonal wire mesh) is not sufficient for predator protection. It can be torn, bitten through, and bent aside by a determined fox. Use:

Welded Galvanised Wire Mesh

• Gauge: Minimum 16-gauge (the lower the number, the thicker the wire)
• Mesh size: Maximum 25mm x 25mm (approximately 1 inch square) — this prevents rats and stoats entering while remaining strong against foxes
• Construction: Properly stapled or bolted to a solid timber frame, with no gaps at corners or joins

Secure Latches

Standard spring latches can be nudged open by foxes. Use:

• Bolts that slide fully home
• Padlocks for overnight security
• Carabiner clips as a secondary fastener

Anti-Dig Apron

A fox that cannot break in or lift a lid will dig. An anti-dig apron prevents this:

• Bury wire mesh 30–45cm deep around the perimeter of the run
• Alternatively, attach a horizontal “apron” of wire mesh to the base of the run walls, extending outward at least 45cm along the ground
• Weight this apron with stones, turf, or bury under a shallow layer of soil

Overhead Cover

The entire run must be covered overhead with the same gauge mesh to protect against birds of prey. A solid or partially solid cover (plywood, Perspex, or fine mesh) also provides shade and weather protection.

The “Safe Space” Issue

Even a fully secure enclosure does not protect rabbits from stress caused by predator proximity. Measures that reduce predator approach:

• Move the hutch away from garden boundaries where foxes patrol
• Install a motion-activated light or water spray deterrent around the enclosure area
• Remove sources of attraction from the garden (compost heaps, fallen fruit, unsecured bins) that draw foxes and rats
• Create visual barriers between the hutch and garden boundary — dense hedging or solid fencing reduces a fox’s sightline to the hutch
• Provide hides within the run so rabbits can get out of sight when stressed

Nighttime Routine

Regardless of how secure your run is, bring rabbits into a locked hutch at night:

• Secure all latches
• Confirm no gaps exist at ground level
• Check for signs of digging attempts in the morning

The RabbitCare App

The RabbitCare App (free on Android) includes a housing security checklist that walks through outdoor enclosure security requirements — helping you identify vulnerabilities before they’re exploited.
