What causes cats to spray?

Cats aren't well equipped to handle confrontation. When confrontation or change happens, they can get stressed. “Spraying,” or urine marking, is their way of telling other cats or new people to back off without a direct confrontation. Your cat may be spraying to communicate about territory or something else.

Why has my cat started spraying in the house?

Spraying indoors is a sign that the cat is feeling stressed and needs to make itself feel more secure, surrounding itself by its own scent. As indoor spraying indicates that the cat feels threatened by something. The most common cause is the presence of other cats, either within the house or in the neighbourhood.
