What is the most common first symptom of intervertebral disc disease in cats?

The most common signs are changes in gait, such as a wobbly walk or limping on one side, and may include flinching or crying out when the back is touched. If you notice anything abnormal, consult your vet for an evaluation.

What imaging tests does the vet typically perform?

X-rays are typically used first to assess the vertebral bones. If spinal cord compression is suspected, CT or MRI will be arranged for further evaluation to determine the extent of disc or spinal cord involvement.

How do I choose between conservative treatment and surgery?

The choice depends on symptom severity and imaging findings. Mild cases may be managed initially with rest and medication, while severe or progressively worsening cases may require surgery. Please follow your vet's assessment.

What information should I prepare before the appointment?

It is recommended to bring a record of when symptoms started and how they changed, front- and side-view walking videos, a list of current medications, and any existing imaging or medical records. This helps the vet make faster decisions and arrange appropriate tests.

How much do the tests and treatment usually cost?

Costs vary by clinic and region — ask your vet for an estimate before proceeding.

Cat Intervertebral Disc Disease (IVDD): Symptoms, MRI/CT Diagnosis & Treatment Guide [2025]

Intervertebral disc disease (IVDD) is less common in cats than in dogs, but can cause hind limb weakness or paralysis. Symptoms may develop acutely or gradually. Treatment ranges from conservative management to surgery, depending on severity.

When to See a Vet

Seek Emergency Care Immediately

•Sudden complete inability to move or stand on hind limbs
•Persistent inability to urinate or defecate on their own for several hours
•Signs of altered consciousness or rapid deterioration within a short period

Schedule a Vet Visit Soon (within 24–72 hours)

•Noticeable limping but still able to walk short distances
•Visible flinching or vocalizing when the back is touched
•Reduced activity level but still partially alert and eating

01What symptoms indicate a problem?

Disc disease commonly causes movement and pain changes related to the spinal cord or nerves, with varied presentations that can sometimes appear suddenly.

Unsteady or wobbly gait, prone to stumbling or slipping
Limping on one or more limbs, or reluctance to bear weight on a leg
Obvious pain response — flinching or crying out — when the back or spine is touched
Reduced activity, lethargy, or decreased appetite
Possible localised loss of sensation or motor function (e.g. difficulty lifting a leg)
If you cannot assess the severity of symptoms, seek a veterinary evaluation as soon as possible

Seek emergency care immediately if you notice the following symptoms:

⚠️ Sudden complete inability to move or stand on the hind limbs
⚠️ Persistent inability to urinate or defecate on their own for several hours
⚠️ Altered consciousness or rapid deterioration within a short period

02How to assess the situation at home? Key observations and when to go to the emergency clinic

Home observations and records help the vet quickly understand the condition and how it has progressed.

Note the exact time symptoms began and each subsequent worsening episode
Record front- and side-view walking videos on your phone, noting the distance walked
Track specific values or frequencies for appetite, water intake, and weight changes
Monitor the frequency of urination and defecation, and whether there is difficulty or need for assistance
Avoid moving or forcibly carrying your cat to minimise the risk of secondary injury
Take videos and arrange a specialist appointment at a clinic with imaging capabilities as soon as possible

03How will the vet make a diagnosis? Common diagnostic tests

The vet will progress from a physical examination to advanced imaging to identify the source of pain and the degree of neurological damage.

Physical and neurological examination

assess reflexes, sensation, and the location of pain

X-ray

initial evaluation of vertebral bone morphology and degenerative changes

CT or MRI

to clarify disc herniation, spinal cord compression, or soft tissue lesions

Blood and biochemistry panel

assess overall health and surgical risk

Referral to a neurology or imaging specialist if required

If spinal cord compression is suspected, evaluation at a specialist hospital with MRI capability is recommended

04How is treatment managed after diagnosis? Medications, adjustments, and care guide

Treatment may be conservative or surgical; both approaches require regular follow-up to monitor functional recovery and potential complications.

Conservative management: strict rest with restriction of jumping and vigorous activity
The vet will advise on pain relief or anti-inflammatory medications and an observation period based on your cat's condition
If surgery is needed, a full pre-operative assessment and risk explanation will be provided first
Regular check-ups and functional assessments are required during post-operative or conservative treatment
Home care includes gentle rehabilitation, wound care, and avoiding unsupported handling of your cat
If there is any deterioration or uncertainty, specialist or neurology follow-up is recommended

05What should I prepare before the vet visit? Key information to help the vet reach a diagnosis quickly

Record when symptoms first appeared, their frequency, changes over time, and whether onset was sudden

Record front- and side-view walking videos and bring them to the appointment

Note specific frequencies and changes in appetite, water intake, and elimination habits

Bring a list of all current medications and supplements

Bring any existing imaging reports or medical records (if available)

Use a secure carrier and call ahead to describe the symptoms and level of urgency
