If your cat is spraying in the house, it could be a sign of stress. Their environment and proximity to other cats could both be factors in their spraying behaviour.
Spraying in multi-cat homes
In multi-cat homes, cats might start to spray if they do not have access to their own litter tray. Cats don’t like to share toilets, so as a rule, you should have enough litter trays for each cat, plus one extra for good measure.
Spraying might also occur in multi-cat homes if there aren’t enough beds, feeding bowls and cat toys. Your cats might start to spray to claim resources as their own if there aren’t enough to go around.
Conflict with neighbouring cats
Spraying in the house could indicate conflict with other cats in the neighbourhood. If you have a standard, non-selective cat flap, the neighbours’ cats could be coming in through the cat flap, causing stress to your pet. Your cat might spray to mark their territory as a warning to intruders.
Install a SureFlap Microchip Cat Flap to keep intruder cats out and the spraying problem should stop.
Cat toileting facilities
Some cats might spray in the home if they do not have a suitable outdoor toilet to use. Create an outdoor cat toilet by digging a hole in a sheltered position in your garden and filling it with loose sand.
If you use an indoor litter tray, your cat might start to spray if you change the type of litter you use. Try to avoid switching between different types of litter and stick to an odourless mineral based litter that is not wood or pulp pellets.
Changes to your home environment
Cats can find changes to your home environment stressful, which could cause them to spray. If you move house, confine your cat to one room initially to give them time to adjust to their new home. When introducing new furniture to your home, give it plenty of time to air before your cat gets near it to allow any chemical smells to dissipate.
If you have tried removing all these sources of possible stress and your cat is still spraying, speak to your vet for advice as your cat may have feline cystitis.
