Cat Behavioural Problems: Understanding and Addressing Common Issues

Many common cat behaviour problems have welfare roots in unmet needs or medical conditions. Evidence-based approaches address causes rather than symptoms for lasting improvement.

Key Facts

Inappropriate elimination (urinating or defecating outside the litter box) is the most common reason cats are surrendered to shelters
House soiling can result from medical conditions (UTI, CKD, diabetes), litter box aversion, or marking behaviour
Aggression between cats in multi-cat households reflects inadequate space, resources, or incompatible social groupings
Inter-cat aggression in previously compatible pairs is often triggered by a stressful event — redirected aggression, illness, or environmental change
Compulsive disorders in cats include excessive grooming (psychogenic alopecia) and wool-sucking, often linked to anxiety
Scratching is normal feline behaviour serving communication and claw maintenance — appropriate provision of scratching surfaces prevents furniture damage
Nocturnal activity is natural for cats — enrichment and feeding schedules can shift activity timing to owner preference
Most cat behaviour problems are solvable with correct diagnosis of the underlying cause and appropriate environmental modification

Welfare Considerations

Cat behaviour problems are usually welfare problems in disguise. Inappropriate elimination often signals physical discomfort (UTI, painful defecation) or psychological distress (litter box aversion, territorial stress). Aggression between cats reflects crowding, resource competition, or relationship breakdown — all amenable to environmental intervention. Psychogenic alopecia represents chronic anxiety requiring both environmental and sometimes medical management. The critical welfare insight is that behaviour problems rarely occur without cause — identifying and addressing the underlying welfare deficit resolves the behaviour and improves the cat's quality of life simultaneously. Punishment-based responses to behaviour problems worsen the underlying anxiety and damage the human-animal bond without addressing root causes.

What You Can Do

Rule out medical causes first for any new behaviour problem — visit your vet before assuming a behavioural origin
Consult a certified cat behaviour consultant for persistent problems
Ensure litter box resources are adequate: one per cat plus one, kept meticulously clean
Provide adequate scratching surfaces in appropriate locations before problems begin
In multi-cat homes, ensure sufficient space and resources for all cats to avoid without conflict
Never punish inappropriate elimination or aggression — address the cause instead
Consider pheromone therapy (Feliway) for anxiety-related behaviour problems as an adjunct to environmental management
