Bird Cage Safety Checklist: The Cage, the Hardware and the Room, from the Vets

The cage

Check	Why	Source
Bar spacing matches the bird: 1/2 in budgies, lovebirds, parrotlets, cockatiels; 3/4 in conures and similar; 1 in greys and Amazons; 1 1/2 in macaws	A head between the bars is the cage injury	Merck Veterinary Manual table
Bars thick enough that the bird cannot bend them	A bent bar is a wider gap	PetMD (Dr. Latas); Prevue publishes gauge
No converging bars, domed tops or decorative scrollwork a toe or head can wedge in	Entrapment	PetMD (Dr. Latas)
Rectangular, wider than tall	Round cages give no corner and little flight	VCA; Merck owner page
At least the Merck minimum; 1.5 times the wingspan in every direction	Room to stretch and move	Merck; MSPCA/AAV guidance
No chipped or flaking coating; no rust	Birds swallow chips; older coatings can contain zinc	VCA Housing Small Birds
Not galvanized, or wire-brushed and inspected if it is	Galvanized coating toxic to cockatiels at 2 mg a week	Howard 1992 (JAVMA); Niles Animal Hospital
No white rust (zinc corrosion) anywhere	Toxic	Niles Animal Hospital
Wire floor covered, or a grille the feet can stand on	Foot injury	MSPCA/AAV; VCA
Not wood, wicker or bamboo for a parrot	Chewed through; cannot be disinfected	VCA
Doors that latch against a beak; locks on a large parrot's cage	Escapes into a room with the hazards below	Prevue (bird-proof locks on the Imperial); our inference from the hazards list

The hardware

Check	Why	Source
No galvanized clips, quick links, chains or dishes	Zinc; especially dishes holding acidic food	Niles Animal Hospital
Stainless dishes for large birds; non-toxic, sturdy, washed daily for all	Chewed plastic; bacteria	VCA
Water shallow enough that a small bird cannot get stuck	Drowning and chilling	VCA
No lead: curtain weights, fishing weights, stained-glass solder, pre-1978 paint within reach	Lead poisoning	VCA Household Hazards
Imported toys and cage parts checked for lead and zinc	Some contain both	VCA Household Hazards
Natural wood perches of varied diameter; no sandpaper covers; natural cotton or hemp rope only, watched for strands	Foot sores; toe entanglement	VCA
Perch woods from the safe list; none from the avoid list (apricot, cherry, nectarine, peach, prune, plum, oak, laurel, pitch pine, yew)	Toxic woods	VCA

What goes inside

Toys and swings come out of a travel cage before a car trip (VCA transport page). Rope and fabric toys are checked for loose strands daily (VCA). Mirrors and bells are a matter of opinion among owners and we found no veterinary source for or against them; a bell with a clapper a bird can remove is a small metal part, and small metal parts are the zinc and lead question above. Paper on the tray, changed daily, so droppings can be seen (VCA). No grit for parrots (PetMD). The perch guide and dish guide have the picks that pass.

The room

Check	Why	Source
No bird in the kitchen, ever, and no non-stick cookware, drip pans, irons, ironing-board covers, waffle irons, heat lamps or space heaters with PTFE coatings heated anywhere the fumes reach	PTFE fumes kill birds, sometimes at ordinary cooking temperatures; sudden death; budgies most sensitive; VCA says the only reliable prevention is avoiding PTFE around birds	VCA, Teflon Toxicity in Birds
Not the laundry room	Same fumes from heating elements and irons	VCA, Teflon Toxicity
No smoke, aerosols, scented candles, paint or cleaning fumes in the room	Airway irritation and poisoning	VCA Household Hazards
Ceiling fans off whenever the bird is out	Never let a bird fly with a fan running	VCA Household Hazards
Toilets closed, sinks and tubs empty, pots covered	Drowning	VCA Household Hazards
Windows and mirrors marked or covered when the bird is out	Collisions	VCA Household Hazards
Cats, dogs, ferrets, snakes and lizards never alone with the bird	Predation; a cat scratch is a medical emergency	VCA Household Hazards
Out of the sight and sound of predators, indoors and out	Stress	RSPCA Australia
Away from windows, air conditioners and drafts; comfortable room temperature	Chilling; overheating in sun	Merck owner page; PetMD
Not under a stucco or popcorn ceiling the bird can reach	Ingested ceiling material	VCA Household Hazards
Houseplants checked against a toxic list; none within reach	Poisoning	VCA Household Hazards
No open doors to the outside when the bird is out	Escape	VCA Household Hazards

The night and the car

Ten to fourteen hours of dark, quiet sleep (PetMD), in a room without late television; whether to cover is the one point where Merck's owner page (most birds should not be covered) and PetMD (cover or darken the room) differ, and the placement guide gives both. In the car: never loose, belted in, toys out, no water dish, never left alone in a parked car, no sedatives (VCA transport page), as the carrier guide sets out.

What zinc poisoning looks like, so you call in time

The Niles Animal Hospital sheet describes heavy-metal poisoning in birds as vague and variable: lethargy, weakness, depression, regurgitation, loss of appetite, increased thirst and urination, greenish or discoloured droppings, weight loss, and in lead cases neurological signs; it says diagnosis is by blood level and history and treatment is chelation (calcium EDTA) by a veterinarian. Howard's cockatiels on the high dose died within two weeks. The practical rule is the one at the top: a bird that has been chewing a galvanized or unknown metal and is off colour goes to an avian vet that day, with the metal.

The checklist in one place

Spacing by the Merck table. Gauge the bird cannot bend. No converging bars. Rectangular. No chips, rust or white rust. Not galvanized unless brushed and inspected. Floor covered. Metal, not wood. Latches. Stainless or stated non-toxic hardware. Stainless dishes for big birds. Shallow water. No lead within reach. Natural perches, no sandpaper, natural rope. Safe woods only. Paper changed daily. Not the kitchen, not the laundry. No PTFE heated in the house. No smoke, aerosols or fumes. Fans off. Water covered. Windows marked. Other pets never alone with the bird. Away from drafts and sun. Dark, quiet nights. Belted in the car. The setup guide walks the cage itself; the buying guide runs the checks before the cage is bought.
