Head pressing — when a cat stands facing a wall or solid object and presses its head against it without purpose — is always a neurological emergency. It signals elevated intracranial pressure, hepatic encephalopathy, or a serious brain lesion. Any cat exhibiting this sign needs same-day emergency veterinary evaluation.

What Does Cat Head Pressing Mean?
Head pressing is a distinct, compulsive behavior in which the cat places its forehead against a wall, corner, or other surface and maintains pressure, sometimes for minutes at a time. It is not to be confused with head bunting (the affectionate cheek-rubbing cats do voluntarily). Head pressing reflects dysfunction of the forebrain — typically caused by elevated intracranial pressure, toxic encephalopathy, severe metabolic disturbance, or structural brain disease. As described in Ettinger's Textbook of Veterinary Internal Medicine, head pressing is one of several forebrain signs (others include circling, behavioral change, and seizures) that indicate dysfunction rostral to the brainstem. It is uniformly abnormal — there is no benign cause.
Signs That Accompany Head Pressing in Cats
Head pressing rarely occurs in isolation. Owners typically notice:
- Compulsive circling — usually in one direction, toward the side of the lesion
- Behavioral changes — sudden aggression, confusion, apparent blindness
- Seizures — forebrain disease frequently lowers seizure threshold
- Dilated or unequal pupils — asymmetric pupils signal critically elevated intracranial pressure
- Decreased responsiveness or stupor — the cat appears "absent" or difficult to rouse
- Stumbling or ataxia — severe gait disturbance
- Altered vocalization — yowling, crying
The AAFP Senior Care Guidelines, 2021 note that behavioral and neurological changes in older cats — including altered mentation and compulsive repetitive behaviors — should always trigger prompt veterinary evaluation rather than attribution to "aging."
Causes of Head Pressing in Cats
| Cause | Notes |
|---|---|
| Hepatic encephalopathy | Liver failure → ammonia accumulation; most common metabolic cause |
| Hypertensive encephalopathy | Systemic hypertension (from CKD or hyperthyroidism) → brain hemorrhage |
| Intracranial neoplasia | Meningioma (most common feline brain tumor), lymphoma |
| FIP | Neurotropic wet or dry form affecting the brain |
| Thiamine deficiency | All-fish diet, prolonged anorexia → brainstem/forebrain hemorrhage |
| Toxin exposure | Permethrin (flea products for dogs applied to cats), lead, ethylene glycol |
| Head trauma | Car accident, fall from height |
| Inflammatory encephalitis | Immune-mediated or infectious |
Diagnosis — An Emergency
Diagnosis must proceed quickly because several causes (hypertensive crisis, toxin, thiamine deficiency) are reversible if caught early. Emergency workup includes:
- Blood pressure measurement — hypertension (>160 mmHg) is a common, treatable trigger
- Complete blood panel including ammonia (liver function) — $100–250
- Urinalysis — $50–100
- Chest and abdominal radiographs — $150–350
- Brain MRI — gold standard for structural lesions; $1,200–2,500 at a neurology center
- CSF analysis — follows MRI; $200–400
Treatment
Treatment depends on the underlying cause:
- Hypertensive crisis: amlodipine (oral, acts within 24 hours) to reduce blood pressure to target range
- Hepatic encephalopathy: lactulose, rifaximin or metronidazole to reduce ammonia; dietary protein modification; treat underlying liver disease
- Thiamine deficiency: parenteral thiamine IV or IM — dramatic improvement often visible within hours
- FIP: GS-441524 antiviral treatment (12 weeks minimum for neurological form); cost $3,000–8,000+
- Intracranial tumor: palliative corticosteroids; surgical resection or radiation for meningioma at a neurology referral center; cost $3,000–10,000+
- Permethrin toxicity: immediate bath to remove product, IV lipid emulsion, seizure control — true emergency
When to See a Vet
Call your vet today if:
- Your cat is pressing its head against any surface repeatedly
- You notice your cat circling, confused, or apparently blind
- Any sudden behavioral change or unusual compulsive behavior develops
Go to the ER immediately if:
- You see head pressing + any of: seizures, dilated pupils, stupor, or inability to walk
- You applied a dog flea product containing permethrin to your cat
- Your cat has collapsed or is unresponsive

Frequently Asked Questions
Is head pressing in cats always serious? Yes, always. Unlike many cat symptoms that have benign explanations, head pressing has no normal cause. It specifically reflects forebrain dysfunction — elevated pressure, toxic encephalopathy, or structural brain disease. Waiting to see if it passes is not appropriate; same-day emergency evaluation is required.
What is the most common cause of head pressing in cats? Hepatic encephalopathy (from acute liver failure) and hypertensive encephalopathy (from uncontrolled high blood pressure secondary to CKD or hyperthyroidism) are among the most commonly identified reversible causes. Brain tumors and FIP are common non-reversible causes. All require immediate diagnosis to guide treatment.
Can a cat recover from head pressing? Recovery depends entirely on the underlying cause. Thiamine deficiency is highly reversible with prompt treatment — most cats improve within hours. Hypertensive crisis resolves with blood pressure medication. FIP and brain tumors carry more guarded prognoses. Early evaluation dramatically improves the chance of a treatable cause being found.
What does diagnosing head pressing cost in cats? Emergency exam and initial bloodwork: $200–500. Chest/abdominal X-rays: $150–350. Blood pressure measurement: $50–100. Brain MRI: $1,200–2,500. CSF analysis: $200–400. Total workup can run $1,500–3,500 depending on what is found. The cost of not diagnosing a reversible cause is far higher.
What should I do if I see my cat head pressing? Do not wait. Call your vet or nearest emergency animal hospital immediately and describe the behavior. Note whether your cat recently received any flea products (especially dog products), ate a new food, or has had recent illness. While waiting, keep the cat in a safe, quiet space away from stairs or fall hazards.
Still Not Sure if Your Cat Needs a Vet?
