A cat with a suspected spinal injury has about 30 minutes before swelling inside the spinal canal starts to cause damage that surgery cannot fully undo. Two decisions outweigh everything the clinic does later: never lift the cat by the waist or the scruff, and move it on a rigid flat board with the spine held in the position you found it. Lifting a 4 kg cat by the middle of the back bends the injured segment 2 to 3 cm and can turn a bruise into a torn cord.
4 checks in 60 seconds: spine or hip
Most spinal trauma comes from a fall of 2 or more floors, a road strike, or a heavy door closing on the tail base. Pelvic fractures look almost identical from 3 metres away, and roughly 1 in 4 road-strike cats carries both injuries. Run 4 checks in under 60 seconds without moving the cat: pinch one hind toe firmly and count to 2; lift the tail 2 cm and let go; count belly movements for 30 seconds, since normal is 30 to 40 breaths a minute; look for urine on the towel with no squatting posture. A cat that drags both hind legs, has a tail that flops, and leaks urine has a lesion between the 3rd lumbar and 3rd sacral vertebra until a vet says otherwise.
Stiff front legs with weak hind legs point higher, to the neck or mid-back, and that is a 10 out of 10 emergency. Open-mouth breathing, a grunt on every exhale, or a drum-tight belly means the chest may be involved too. Do not hunt for a sore spot by pressing along the spine. A cat that screams when you press has already told you what you needed, and the press itself can shift a fracture by 1 to 2 mm.
3 pieces of fixation, assembled in 5 minutes
You need 3 things, and a soft carrier is not one. First, a rigid board: a wooden cutting board, a shelf, a folded ironing board, or 2 layers of heavy cardboard taped together; press the middle with one hand and it must not flex more than 5 mm. Second, padding no thicker than 2 cm, since 5 cm of foam lets the spine sag. Third, 3 strips of tape, with 2 side rolls if the cat is still.
Slide the board under the cat instead of lifting the cat onto the board. Two people finish this in 30 seconds: one holds the shoulders, the other slides the board under the hips. Nose, sternum and tail base stay in one straight line. Tape across the shoulders and across the hips, never across the belly, and leave the chest free so the cat can still take 40 breaths a minute.
The 30-minute clock is not a metaphor
Cord swelling builds through the first 30 to 60 minutes. A cat that still has deep pain in the toes at 48 hours has a far better chance of walking again than one that does not, and that difference is often settled within the first 2 hours. Most referral hospitals want a spinal case on the table within 2 to 4 hours of the accident. Call before you drive and give 4 facts: accident time, no deep pain in the hind feet, hard-board transfer, drive time in minutes. A clinic that knows a spinal case is 25 minutes out will meet you at the door.
Drive slower than feels right. A pothole at 40 km per hour sends a jolt straight up the spine. Hold 30 to 40 km per hour on broken roads, put one person in the back with a hand on the board edge, and skip the roadside leg check. Rechecking costs 10 minutes and changes nothing.
What not to do in the first hour
Six habits do the damage. Do not carry the cat by the waist; that is the most common way a stable fracture becomes a torn cord. Do not pull the tail to test it. Do not wash road dirt off, because wet fur drops body temperature 1 to 2 degrees Celsius in 10 minutes and cold worsens clotting. Do not give human painkillers: 500 mg acetaminophen or 200 mg ibuprofen can kill a 4 kg cat. Do not offer food or water, since anesthesia may follow within 2 hours. Do not massage or stretch the hind legs.
Grade, padding, and arrival window
| Grade | Hind toe withdrawal | Padding depth (cm) | Arrival target (min) |
|---|---|---|---|
| 1 | Yes, under 1 second | 2 | 60 |
| 2 | No, tail flaccid | 2 | 30 |
| 3 | No, hind feet cool | 3 | 20 |
| 4 | Not testable, open-mouth breathing | 3 | 15 |
| 5 | Yes, urine leaking only | 1 | 90 |
Grade 3 and 4 cats travel with the head raised 10 to 15 degrees and no collar. Take the collar off before taping, since a trapped collar edge presses on the jugular vein.
The first 90 minutes at the clinic
Expect 3 imaging steps. X-rays take 10 to 15 minutes and show bone alignment, not the cord. CT takes 20 to 40 minutes under sedation or full anesthesia and shows fragments in 1 mm slices. MRI takes 45 to 60 minutes and is the only study that shows swelling inside the cord, which is why it is usually booked for a cat that still cannot feel its toes at 24 hours. Blood work and a bladder scan add 15 minutes. Typical US prices run 150 to 400 dollars for X-rays, 600 to 1,200 for CT, and 1,200 to 2,500 for MRI; the first 24 hours of hospital care adds another 800 to 1,500.
Bladder, skin, and the 8-week rehab line
A paralysed cat cannot empty its bladder. Express it every 6 to 8 hours, 3 to 4 times a day, at 10 to 20 ml per kg per squeeze, so 40 to 80 ml for a 4 kg cat, until the leak reflex returns. Turn the cat every 4 hours and check 2 pressure points, the outside of the hock and the point of the hip. Rehab starts in week 2 with 3 sessions of 10 minutes a day and runs to week 8; most vets recheck deep pain at 2, 4 and 8 weeks. A cat with no change at 8 weeks is unlikely to improve, and a cart fitted at 12 weeks is a reasonable plan.
5 steps to run right now
- Call the nearest 24-hour clinic and say spinal injury, no deep pain, 25 minutes out.
- Lay a rigid board beside the cat and slide it under, never lift the cat up.
- Tape at the shoulders and the hips, leave the chest free, remove the collar.
- Cover with 1 thin towel and hold the car at 30 to 40 km per hour.
- Hand over the accident time and the 4 checks; skip food, water and painkillers.
If the accident involved a plant, a human drug or a household cleaner, bring the packaging and check the toxic plant lookup. Cats that fall from balconies often chew lilies within the hour, which changes the drug plan; see the plant emergency guide. The handling routine in more detail sits in spinal injury handling.

Frequently asked
Can I move a cat with a spinal injury in a carrier?
A soft-sided carrier is the wrong container because the floor bends under the cat. Use a rigid board no longer than the cat plus 10 cm, lay a towel of 2 cm or less on it, and slide the board under the body. A plastic carrier with a hard flat base works only if you can slide the cat onto the base without lifting, which usually means taking the top half off first.
How long can I wait before driving to the clinic?
Do not wait at all. Cord swelling builds over the first 30 to 60 minutes and most referral hospitals want the cat on the table within 2 to 4 hours. Call while you are still kneeling beside the cat, then drive. A 20 minute delay to find a better carrier or to finish a phone debate is the kind of delay that decides whether the cat walks again.
Is it true that prednisone or a human painkiller helps on the way?
No. Steroid decisions belong to the vet, who needs to see the neurologic exam before any drug is given, and human painkillers are dangerous: 500 mg acetaminophen or 200 mg ibuprofen can kill a 4 kg cat. Give nothing by mouth, because anesthesia may follow within 2 hours of arrival and a full stomach raises the risk of vomiting under induction.
