What is it?
This is what we call all the injuries that a cat presents after a fall from a window, balcony or roof. It's a very common accident in the city, especially on the first sunny days when you open the windows.
The cat turns around in the air and lands on its legs, but this does not protect it: the shock is distributed across the ribcage, face and limbs. The most serious lesions are often invisible from the outside.
A cat that gets up and walks after a fall may have bruised lungs, a fractured palate, or internal bleeding. Any cat that has fallen, even apparently unharmed, should be examined by a veterinarian.
Key point
Emergency. A fallen cat that appears unharmed may have serious internal injuries: it must be examined the same day.
Commonly observed signs
These signs are neither exhaustive nor specific. Only a veterinarian can establish a diagnosis.
Related signs — each one links to its page:
Rapid, shallow or difficult breathing: a sign of damage to the lungs or air in the rib cage.
Nosebleed, jaw that no longer closes properly, difficulty swallowing or closing the mouth: suggests a fracture of the face or palate.
Frank lameness, hanging leg, refusal to place a limb.
Pain in the back or abdomen, cat growling or tensing up at the slightest contact.
Pale gums, cold and prostrate cat: possible internal bleeding.
Difficulty urinating or bladder not emptied in the following hours.
Lying cat who does not get up, or who drags his hindquarters.
Sometimes, no visible signs for several hours: this is the trap of this syndrome.
When to consult without delay
This list does not replace veterinary advice. It gathers situations that justify a prompt consultation.
Causes and risk factors
Falling from an open window, often in a tilted position: the cat slips in the opening and gets stuck or falls.
Fall from a balcony, railing, ledge or roof.
Lose balance when chasing a bird or insect, or when startled at a noise.
Unsecured mosquito net that gives way under the weight of the animal.
Slippery surface on a freshly cleaned or wet edge.
Living in an upstairs apartment, with accessible windows or balconies.
Young, playful cat, comfortable at height and not very aware of heights.
Elderly or visually impaired cat who has difficulty judging distances.
Tilt-and-turn windows are particularly dangerous.
Beautiful days, prolonged ventilation, lack of security.
Unsterilized cat, more inclined to try to reach the outside.
Diagnosis and care
Diagnosis is the veterinarian's responsibility, based on clinical examination and laboratory tests. Care is decided case by case.
Handle the cat as little as possible and transport it on a rigid support, in a closed crate, without holding it in your arms against your body.
Do not give him food, water, or human medicine, especially painkillers: surgery may be necessary within the hour.
Go straight to the vet, even if the cat is walking and seems fine.
The assessment includes a complete examination of the mouth and face, listening to the lungs, x-rays of the chest and limbs, and often an ultrasound of the abdomen.
Certain injuries, such as pulmonary contusion, are only fully visible a few hours after the fall: clinical monitoring is frequently suggested.
Treatment
The priority is stabilization: oxygen, perfusion, pain management with veterinary painkillers.
If there is air or blood in the rib cage, the veterinarian will evacuate it before any other intervention.
Fractures of the limbs, jaw or palate are surgically repaired once the cat is stable.
Facial wounds and broken teeth are treated at the same time when possible.
Assisted feeding may be necessary for a few days when the mouth is affected.
Strict rest in a confined space is an integral part of the treatment for several weeks.
Treatment depends on the cause and the animal's condition: it must be determined by a veterinarian. No self-medication.
Prevention
Prevention is the real answer here: almost all of these falls are avoidable.
Equip windows and balconies with heavy-duty protective nets or mosquito nets firmly attached to a frame, not simple adhesive mosquito nets.
Avoid windows that are ajar in the tilt-and-turn position, or install specific protection in the corner opening: a cat can get stuck there and be seriously injured.
Do not leave a cat alone on an unprotected balcony, no matter how careful it usually is.
Also secure windows on low floors: a fall from a low height can be more traumatic than a fall from higher heights, because the cat does not have time to turn around.
Never rely on the idea that “cats always land on their feet”: it’s true, and it doesn’t protect them.
Possible complications
Contusion of the lungs, air or blood in the rib cage, with delayed respiratory distress.
Rupture of internal organs and hemorrhage.
Fracture of the hard palate, jaw, pelvis or limbs.
Bladder rupture, with inability to urinate.
Hernia of the diaphragm, sometimes discovered late.
Spinal damage with paralysis.
Chronic lameness or osteoarthritis in a poorly consolidated joint.
When to see a veterinarian
Your cat has fallen from a window, balcony or roof: consult the same day, even if it gets up and walks normally.
He breathes quickly, with difficulty, or remains open-mouthed.
He has a nosebleed or no longer closes his jaw properly.
He refuses to lay a paw or howls upon contact.
His gums are pale, he is cold and prostrate.
He hasn't urinated since the fall.
He seemed fine then deteriorates in the hours that follow: return to the vet immediately.
Prognosis
Many cats survive a fall and return to normal life, provided they are examined quickly and monitored for the first twenty-four hours.
The prognosis depends mainly on lesions of the thorax and abdomen, more than on visible fractures.
Spinal damage and internal hemorrhages significantly worsen the prognosis.
Most tragedies are due to an unreported fall or a postponed consultation because the cat “seemed fine”.
Frequently asked questions
My cat fell from the second floor and is walking: do I really need to consult?
Yes, the same day. The most dangerous injuries after a fall — bruised lungs, internal bleeding, fractured palate — are not visible from the outside and sometimes appear several hours later.
Is a fall from a short height less serious?
Not necessarily. Below a certain height, the cat does not have time to turn around and recover: injuries can be more severe than in a fall from higher heights. Any fall warrants an examination.
How to secure a window without condemning everything?
Protective nets for balconies and mosquito nets mounted on rigid frames allow safe ventilation. Windows in a tilt-and-turn position require specific protection of the corner opening, where cats get stuck.
Can I give him some painkiller while I wait?
No, never. Human painkillers are toxic to the cat and anesthesia may be necessary within the hour. Transport him calmly in a crate and let the vet manage the pain.
