Cat litter smell from neighbours: how to raise it tactfully

You open your front door and notice it straight away: a sharp smell of cat urine on the landing, in the stairwell or drifting through the vent. A cat litter smell from neighbours is an awkward thing to bring up. Yet there is often a simple cause and a simple fix. This article explains where the smell tends to come from, how to raise it tactfully and what the rules in the UK say in general terms.

Why your neighbours may not notice it

When you live with a smell every day, your nose adapts to it, so your neighbours may barely notice it at home. You come in fresh and pick it up at once.

Often the tray is not cleaned often enough, there are more cats than trays, or the tray sits where the air flows outwards, such as near the front door, on a balcony or in a shared corridor. Sometimes a cat wees outside the tray because of stress or a bladder problem.

Start by showing understanding

Assume your neighbours are not aware of it. Describe what you smell and where, and keep the focus on the smell rather than on how they live. For example:

"I wanted to mention something slightly awkward. Lately we have been noticing quite a strong cat smell on the landing, especially in the evenings. I suspect you might not notice it from inside. Could we have a think together about where it might be coming from?"

Things you could ask for

For example:

• More frequent cleaning. Scooping daily and regularly replacing all the litter often makes the biggest difference.

• A different spot for the tray. Not by the front door, on a balcony or in a shared space, but somewhere indoors where the air does not drift towards neighbours.

• A covered tray or different litter. A hooded tray and a good odour-control litter keep a lot of the smell in.

• A vet check if the cat goes outside the tray. There may be a health problem, and cleaning alone will not solve that.

Start small and agree to check in after a few weeks.

What the rules say in general terms

In England and Wales, the Environmental Protection Act 1990 lists statutory nuisances that your council's environmental health team must look into when it receives a complaint. These include premises kept in a state that is prejudicial to health or a nuisance, and an animal kept in such a place or manner as to be prejudicial to health or a nuisance. Whether a smell reaches that level depends on how strong it is, how often it happens and for how long.

If you rent, your tenancy agreement is likely to include a clause about not causing a nuisance, and your landlord or housing association can speak to a tenant about ongoing problems. In a block of flats, the lease or building rules often say that nothing should be left in communal areas. If you suspect an animal is being neglected, contact the RSPCA on 0300 1234 999 in England and Wales, the Scottish SPCA in Scotland, or your local council in Northern Ireland. Scotland and Northern Ireland have their own versions of these rules. This is general information, not legal advice. Citizens Advice can help with your own situation.

Keep a simple log

If the smell continues after you have talked, keep a log for a few weeks: the date, time, where you noticed it, how strong it was and what it meant for you, such as keeping windows shut. Do not photograph your neighbours' home or post about it in a local social media group.

In practice

When the smell says more. In Reading, neighbours reported bad smells and fleas coming from a privately rented house. The council's environmental protection team and animal warden found floors covered in cat faeces and urine and removed dozens of cats. The occupants later received suspended sentences and a ten-year ban on keeping cats and dogs (source). Most cat smells are simply about cleaning, but worsening smells with signs of neglect are worth reporting.

Mediation is available in many areas. A review for the Joseph Rowntree Foundation found that local community mediation services in the UK handle around 16,000 neighbour disputes a year, and that roughly half the population has access to one (source). A conversation with a neutral mediator is usually quicker and gentler than any formal process.

If you cannot sort it out together

First send a second, calm message that refers back to your conversation. If that does not help, contact a community mediation service. For a rented home or shared area, let the landlord, housing association or managing agent know. Severe, ongoing smells can be reported to environmental health. If you ever feel threatened, do not argue: call 999 in an emergency, or 101 for non-urgent police matters.
