TL;DR: High-Rise Syndrome is a life-threatening emergency involving internal and orthopedic injuries after a fall; immediate veterinary care is required if your cat cannot walk or move normally.
What is High-Rise Syndrome and how does it affect my cat?
When a cat falls from a balcony or window, the resulting injuries are collectively known as High-Rise Syndrome and often include:
- Orthopedic injuries such as broken limbs or a shattered jaw.
- Internal injuries like a collapsed lung (pneumothorax) or internal bleeding.
- Serious spinal injury, multiple fractures, or severe neurological shock indicated by an inability to walk.
Is it a veterinary emergency if my cat falls and cannot walk?
Urgency Level: High. This is a life-threatening emergency. Even if you do not see blood, the impact from a fall can cause:
- Internal organs to rupture or air pockets to form in the chest cavity, making breathing impossible.
- Red-flag symptoms, such as the inability to use legs, that require immediate medical intervention.
- The need for rapid stabilization, pain management, and diagnostic imaging by a veterinarian.
How can taking a photo or video help the vet triage my cat?
Taking a quick photo or a 5-second video of your cat’s current posture before moving them can be incredibly helpful for the veterinary team by:
- Allowing the triage nurse to see exactly how the cat was positioning their limbs and spine immediately after the trauma.
- Helping the vet determine if the issue is neurological or musculoskeletal before they even begin their physical exam.
- Saving precious time during the stabilization process through immediate visual evidence.
Clinical Context (Merck Veterinary Manual)
When a cat falls from a balcony and cannot walk, minimize movement of the head, neck, and spine. Restrain the cat and use a flat, firm board for support during transport to the hospital. Posterior paresis or paralysis, along with urinary and fecal incontinence, may be present due to spinal cord damage. Initial paralysis signs may resolve within 3-5 days as swelling diminishes. Initiate supportive therapy, including anti-inflammatory medication (methylprednisolone sodium succinate may be beneficial in acute cases), pain management, IV fluid therapy, nutritional support, and cage rest.
