# Why Is My Cat Sneezing UK?

**Occasional sneezing is normal** — dust, litter, or strong scents trigger a reflex. **Persistent sneezing with discharge, eye problems, fever, or appetite loss** needs a vet — often feline upper respiratory infection (cat flu), dental disease, or chronic rhinitis. Kittens and unvaccinated cats need prompt assessment.

## Normal sneezing vs illness

A single sneeze clears the nose — like in people. UK indoor cats may sneeze after:

- **Dusty litter** or renovation dust
- **Strong perfume, spray, or cleaning products**
- **Pollen** in open windows during spring

**Concerning patterns:**

- Sneezing **many times daily** for **more than 3–5 days**
- **Yellow, green, or bloody** nasal discharge
- **Eye discharge or squinting** — ulcer risk
- **Open-mouth breathing** — see [Cat breathing fast](/health/cat-breathing-fast)
- **[Not eating](/health/cat-not-eating)** or lethargy
- **Kittens** from shelters — fast progression

## Common causes in UK cats

### Feline upper respiratory infection (cat flu)

According to the PDSA, **feline herpesvirus (FHV-1)** and **calicivirus (FCV)** cause the classic "cat cold" — sneezing, runny nose, conjunctivitis, mouth ulcers in some FCV strains.

Spread occurs in:

- Multi-cat households
- Boarding catteries
- Rescue centres

[Vaccination](/health/cat-vaccination-schedule-uk) reduces severity but does not prevent all strains. See [Cat respiratory infection UK](/health/cat-respiratory-infection-uk).

### Chronic rhinitis

Some cats develop **long-term nasal inflammation** after earlier flu — intermittent sneezing and congestion for life. Management is veterinary — not repeated human cold medicines.

### Dental disease

Tooth root abscesses can drain into the nasal cavity — sneezing with **one-sided discharge** and [mouth pain](/health/mouth-ulcers-in-cats-uk). [Cat dental care](/health/cat-dental-care-uk) prevents many cases.

### Foreign body

Grass seeds or litter lodged in the nose cause sudden violent sneezing — one nostril often affected.

### Allergies

Less common than in dogs but **environmental allergies** occur — seasonal pattern, itch, or clear discharge.

## What not to do

- **Never give human cold medicines** — paracetamol kills cats ([cat paracetamol guide](/health/can-i-give-my-cat-paracetamol))
- Do not delay kittens with eye/nose discharge — dehydration develops quickly

## Vet diagnosis and treatment

Your vet may check:

- Temperature and lymph nodes
- Eyes and mouth for ulcers
- Teeth and gums
- Consider swabs or imaging in chronic cases

Treatment may include:

- **Antibiotics** for secondary bacterial infection
- **Antiviral or eye drops** — vet prescribed only
- **Fluids and feeding support** if not eating
- **Dental extractions** if tooth root disease

## Home care while waiting for appointment

- Use **dust-free litter**
- Stop **strong air fresheners**
- **Steam** from a shower room (not hot direct steam on cat) may loosen secretions — optional
- Wipe nose gently with damp cotton wool
- Encourage eating with warm smelly food

## FAQs

### Why is my cat sneezing?

Dust, litter particles, perfume, and pollen cause occasional sneezes. Persistent sneezing with nasal discharge, eye watering, or fever often indicates feline upper respiratory infection, chronic rhinitis, or dental disease.

### Can cats catch colds from humans?

Human cold viruses usually do not infect cats. Feline 'cat flu' is caused by feline herpesvirus and calicivirus spread between cats — common in multi-cat homes and rescues.

### When should I take my sneezing cat to the vet?

Book a vet visit if sneezing lasts more than a few days, includes coloured or bloody discharge, eye ulcers, open-mouth breathing, reduced appetite, or affects kittens and unvaccinated cats.

### How is sneezing in cats treated?

Treatment depends on cause — antibiotics for secondary bacterial infection, antivirals in some cases, dental treatment if tooth root abscess, and environmental management for chronic rhinitis. Diagnosis requires vet examination.
