Stress In Domestic Cats: New Review Discusses Causes And Management

Pet cats can suffer from stress triggered by a variety of events and situations, including conflicts with other cats and changes to routine. While cats can adapt, sometimes the stress can be too much, with negative effects on their health.

Writing in the Journal of Feline Medicine and Surgery, a group of veterinarians from the Autonomous University of Barcelona, Spain, explains that stress can impoverish the health of pet cats and increase their risk of disease.

The authors say that stress in pet cats can lead to behavior changes that are so difficult to manage that owners end up relinquishing them or having them euthanized.

In their paper, they discuss the causes and effects of stress in pet cats and strategies on how to prevent and reduce it.

Some of the main causes of stress that they discuss include changes to the pets’ environment, a barren environment, poor relationships with humans, conflicts with other cats and lack of control and predictability.

The authors note that other new changes – such as the arrival of a new member of the household, or a change in the daily routine – may also be stressful for the family’s feline pet.

Effects of stress in cats

In cats, stress distorts normal behavior – leading to reduction or excess of it. Generally, stress causes a domestic cat to become less active and playful and engage in markedly fewer positive interactions with other cats and humans.

The authors note that stress can also cause pet cats to eat less – or more, in some circumstances – than usual.

Stress can also trigger compulsive behavior in domestic cats, such as over-grooming, to the point where the animal loses its fur, showing patches of bare skin. But sometimes, stress can have the opposite effect, causing the cat to be neglectful about grooming.

Another sign of stress in a pet cat is increased urine spraying and increased vigilance – the animal can also become a lot more vocal than usual.

Cats are naturally curious and social animals, but when stressed, they may stop exploring and hide away for long periods of time. They can also become more aggressive.

Often, owners do not realize that stress is the reason their pet is behaving like this, say the authors, especially if there are no other, more obvious, signs.

Reducing conflict

In their review, the authors cover a range of strategies that owners can use to help reduce stress in their pet cat.

For example, they describe a three-phase method for reducing conflict between cats under the same roof.

It is important, to begin with, the cats are kept in separate parts of the house – each with its own space, litter tray, food and water bowls, scratching posts, toys, and so on.

Then, the cats are introduced to each other’s territory (without the other cat being present) – primarily so they can get used to each other’s smell. In this phase, the owner may also take a clean cloth, rub it on the scent gland of one cat, and then rub the scented cloth on the cheek of the other cat. The authors call this phase “olfactory habituation.”

When the cats appear to be relaxed in each other’s territory (still in the absence of the other), the next phase, called “visual habituation,” can begin. In this phase, the cats get to see each other through a safe barrier – for example a mesh door – while they are engaging in the pleasant activity.

The duration of these “visual contact” sessions is gradually increased, until the final phase, “direct contact habituation,” when the mesh or barrier is removed and the animals are allowed to naturally approach each other physically.

Environmental enrichment

Another stress reduction approach that the authors describe is environmental enrichment, where the physical, social and complexity dimensions of the cat’s life are enriched.

In this approach, the cat is given its own space with its own resources (food and water bowls, toys, etc), where it can feel comfortable and relaxed, without feeling threatened by other cats and dogs or other pets.

As cats spend a lot of time foraging, their space should be enriched with “puzzle feeders” and by hiding food in different places.

For cats that spend a lot of time indoors, their toys should be changed frequently to pique their interest and curiosity. Toys that mimic small, moving, catchable prey are particularly effective for this.

Another way to enrich the pet cat’s environment is to install shelves cat trees or platforms so the pet can explore its space vertically as well as horizontally. Cats like using height as a vantage point, and they like to hide in places above the ground.

The authors also mention studies that suggest giving cats places to hide can reduce stress.

Finally, cats, like humans, have different temperaments, and this needs to be considered when deciding strategies for breeding and raising cats, note the authors.
