Feline Fear Overview

Introduction

Fear and anxiety are normal emotions that enable animals to avoid harm. In both states the animal is in a heightened state of arousal in preparation for a negative outcome (e.g. physical harm). The key difference is that in anxiety the threat is anticipated but not actually present, but in fear the threat is present or imminent. An animal may become anxious in a situation in which harm is anticipated, switching to fear when the threat has been identified.

Anxiety is the apprehensive anticipation of future threat or danger accompanied by somatic signs of increased arousal and tension. Anxious animals show increased vigilance and an inability to focus their attention on a specific stimulus. This is because the function of anxiety is to maintain arousal in preparation for threat, whilst the animal gathers information about its environment to determine the source of the potential threat and how best to respond when threat arises. Anxiety is seen in situations in which threat or conflict has previously been experienced, as well as in new situations in which the individual is unable to predict or control what may happen to it. Anxiety can be acute or chronic, and has a pervasive effect on the animal's behaviour. It interferes with the individual's the ability to respond to normal social and environmental cues. When functional, anxiety operates over short periods to enable the individual to prepare for real hazards. Anxiety is dysfunctional when it is sustained in the absence of real threat, leading to persistently increased adrenergic arousal and cortisol release that depletes energy resources and effects such as immune suppression.

Fear is the apprehension of a specific object, person or situation. The source of fear is localisable and identifiable. Its presentation elicits fear and its removal terminates it. Fear is a normal, adaptive experience that enables an individual to avoid harm, and is socially communicated between conspecifics. It is also postulated that there is a strong relationship between fear and frustration. Frustration is experienced when an individual does not achieve an expected positive outcome. So, both fear and frustration relate to an expectation of a negative outcome. Experimentally, animals respond with precisely the same escape response both to fear and frustration, so it is assumed that both experiences relate to the same underlying emotional response.

Phobic fear and panic are intense, abnormal and behaviourally disruptive variants of normal fear and anxiety. Panic and phobia are maladaptive; they lead to a reduction in the animal's ability to cope and perform normal behaviours.

Phobic fear is more intense and long lasting than normal fear. The animal reacts with a high-level of fear even to low level presentations of the fearful stimulus, and then takes a long time to recover from it. Phobic fears do not naturally extinguish with repeated exposure and in fact tend to worsen over time.

Panic attacks are discrete episodes of intense anxiety and arousal. In humans, panic is associated with tachycardia and dyspnoea, which the patient may perceive to be severe enough to be life threatening. Animals are unable to report the feelings associated with panic, so it is assumed to occur based on signs. It tends to occur when an animal is unable to avoid or escape from a situation in which it is already anxious.

Cats will display absolute avoidance of any situation in which panic or phobic fear has previously been experienced and will engage extreme escape responses.

Signs of Fear

Fear is a normal, adaptive experience that enables an individual to avoid harm.

Normal Fear Response Behaviours observed include:

• Facial and postural expressions of fear, directed at fear eliciting stimulus (ear & tail position, piloerection, facial expression, muscular rigidity, posture)
• Sympathetic arousal (graded to threat)
• Muscle tremor
• Flight-escape response (well organised and directed unlike in panic)
• Threat/aggression directed towards stimulus
• There may be urination or defecation (with an apparent loss of control)

When frightened, animals engage in a set of Species Specific Defence Reactions (SSDRs), known as "The Four Fs". These include:

• Fight
• Flight
• Freezing
• "Fiddling about" (performing apparently unrelated behaviours such as grooming)

The cat's primary response to fear is "flight" (avoidance or escape), but they will resort to aggression when escape is impossible in an attempt to drive the fear-eliciting stimulus away. Freezing tends to occur when either flight or fight are impossible, or as the animal evaluates its best option. A cat that is "frozen" but showing signs of stress can launch a sudden attack. Fiddling about may be a form of "self-distraction" in an otherwise inescapable situation of stress, but it may also have some value in diffusing tension in frustration and intraspecific conflict. Fear also potentiates the startle response, so fearful animals will react suddeny to unexpected stimuli and events.

Effects of fear and anxiety

Typical signs observed by owner include:

• The cat being withdrawn, secretive and tending to hide.
• A decrease in interest in social and object play.
• Reluctance to cross open spaces (e.e avoiding outdoors or crossing a room).
• Hiding under objects, or climbing to inaccessible high places.
• Avoiding contact with familiar people and other animals.
• "Jumpiness" (fear potentiated startle response).
• Low-threshold flight response

Behavioural problems relating to fear and anxiety include:

• Indoor marking behaviours, such as urine spraying
• Loss of house training, due to some fearful association with the latrine location
• Defensive aggression
• Wool-eating and other pica
• Over-grooming and self-mutilation

Potential Causes of Emotional Problems

Potential causes of feline fears, phobias and anxiety-related problems include:

• A lack of appropriate socialisation and habituation
• Traumatic experiences
• Genetic influence on temperament (shyness/boldness)
• Old age - loss of competence and an increase in general fearfulness in geriatric cats is well recognised
• Unintentional owner reinforcement of fearful responses

In the veterinary context:

• Cardiac and pulmonary disease are recognised as potential maintaining factors for anxiety.
• Hypothyroidism has been associated with anxiety and compulsive behaviour.
• Pain and fear are associated increased self-defensiveness.
• Hyperthyroidism causes many behavioural changes including increased irritability and aggressiveness.
• Any form of debilitation tends to increase self-defensiveness and aggression.
• Hypoglycaemia is associated with irritability and aggression.

Sickness behaviour, which is mediated by the release of the pro-inflammatory cytokines interleukin-1, interleukin-6, and tumor necrosis factor-alpha. Sickness behaviour includes lethargy, depression, anorexia, energy conservation, anhedonia, cognitive impairment, hyperalgesia, decreased social interaction and anxiety. Many of those are signs associated with emotional disorder. It is therefore wise to consider the possibility that behavioural change is associated with medical disorder.

The Effect of the Environment

The first response of cats to fearful situations is to escape, but the ability to do so is dependent upon familiarity with the environment and the opportunities it provides for escape and avoidance behaviour. This is why success in treating fear-based problems is dependent upon the improving or modifying the environment to enable the cat to more easily escape and avoid fearful situations.

Anxiety can be reduced by making the environment more predictable and controllable for the cat. For example, the owner having more regular routines and patterns of interaction with the cat, and providing the cat with free access to resources such as food, water, latrine sites and outdoor access.

The core zone of the cat’s territory is where it expects to be safe, as this is a place where it would not usually encounter unfamiliar cats. Recognition of the core territory is partially dependent upon pheromone odour signals. The cat expends a lot of time and energy placing face and flank marks within the core territory area, not only to identify elements of the environment as familiar but also to create an appeasing environment for itself. Manipulation of the pheromone environment may also help to improve the environment for cats. This can be achieved by removing undesirable chemical signals (such as scent from previously resident cats, urine spray and claw marks), and the deposition of additional "facial and flank marks" by the owner. This can be done by harvesting facial and flank odour from the resident cats using a cloth, and then wiping this onto suitable places such as door posts and furniture. Synthetic pheromone analogues such as F3 (Feliway), can also be used to recreate or enhance core territory odours. This can trick the cat into perceiving the environment to be safe and secure.

Prevention

As with dogs, the mainstay of prevention of emotional problems in cats is proper socialisation and habituations to stimuli during the sensitive period of development. However, the sensitive socialisation period in cats ends at around 6-7 weeks of age, when kittens are typically still with the breeder. It is therefore essential that breeders take primary responsibility for providing appropriate socialisation and habituation of very small kittens. To develop properly, kittens must meet a wide variety of people and other animals, and be exposed to a wide range of noises and everyday events that are typical of what they will experience in a family home. The greater the discrepancy between the rearing environment and the environment the cat will live in as an adult, the greater the risk of a behavioural problem.

A common set of guidelines for owners could include:

• Only take kittens that have bold, sociable parents.
• Avoid kittens that have been reared in isolation from normal domestic activities (such as in a cattery or shed).
• Let kittens develop in confidence by their normal reinforcing approach and play behaviours with food and play (let them avoid contact if they want to).
• Don't force contact or handling if a kitten is fearful.
• Provide free access to food, water, latrine sites, resting places, and objects to climb and scratch.
• Do not use scolding or physical punishment to deter normal behaviours such as climbing or scratching. Instead, provide outlets for these behaviours and redirect the kitten to them.

The provision of a complex and stimulating environment also reduces the risk of destructiveness and frustration.

Treatment

When dealing with cats who are exhibiting fear-related behaviour problems it is essential for owners to realise that the cat needs to feel in control of the situation and that forcing the cat to confront its fear is likely to lead to a worsening of the problem. However, since avoidance and escape are the primary defence strategies for the cat, it may in some cases it may be necessary to prevent escape from a room whilst desensitisation and counterconditioning techniques are applied. Instead, the cat is given hiding places in the room, so that it has enough control to feel safe, but is still present to be exposed to the stimuli being used in behavioural therapy.

There are four major areas that need to be addressed during any fear related problem:

1) The cat's environment

It is paramount to remember that the environment plays a major role in cat's ability to cope with fear and stress.

2) Behaviour modification techniques

Examples of behavioural modification techniques include habituation, desensitisation, counterconditioning and controlled exposure. Selecting rewards which are of sufficient value to override the fear response can be difficult and, with a high priority for flight as a defence strategy in cats it can be difficult to keep cats in the vicinity of the fear-inducing stimulus during processes such as habituation. Flooding is also a risky approach since the panic induced by the lack of opportunity to escape can potentiate rather than ameliorate the condition. Controlled exposure, desensitisation and counterconditioning can be useful techniques and provided that the fear stimulus is diluted sufficiently it should be possible to over ride the flight response. Introducing a cat to an environment for desensitisation may require leading it in on a body harness and extending lead. The cat should be fully acclimatised to the harness and leash for several weeks before using it in a training situation. For further information on practical aspects of behavioural therapy for fear problems see the problem-specific information linked below.

3) Pharmacological intervention

There a number of reasons why medication may be indicated in cases of feline fear. Cases involving central nervous system pathology, in relation to neurotransmitters, may require medication on a long-term basis and, in situations where the fear-inducing stimuli are either unidentifiable or uncontrollable, long-term or recurring medication may also be indicated. In other cases where medication is necessary as an adjunct to behavioural therapy due to the severity of the fear response and the adverse effect that it has on the learning process, the usual aim is to have short-term drug support.

4) Modifying the owner's reaction

The final part of the equation when dealing with feline fears is to modify the owner’s reaction to the cat’s behaviour. Unintentional reinforcement of fears is most likely to occur in cats when they flee and escape the stimulus, but owner interaction, both vocal and tactile, may be seen by some cats as reward for their response. Punishment is always going to be counterproductive and techniques designed to make the animal “confront its fear” such as flooding have limitations which have already been discussed.
