Introduction
The cat’s primary defence strategy is to escape or avoid conflict. Cats do not possess the same repertoire of appeasement behaviours to halt or modulate intra-specific aggression as are seen in dogs, so physical confrontation at close quarters is likely to escalate quickly and result in serious injury to both parties. To avoid such situations, cats use distance increasing and maintaining behaviours, such as body postures, vocal signals and scent marks. If escape is impossible, then cats will often freeze and deliver a range of threatening behaviours, including postural and vocal signals, designed to repel or hold the threat at bay. Meanwhile, the cat will re-evaluate its opportunities for escape. Attacks may be sudden and brief, and again aimed at repelling the threat so as to re-open an opportunity for escape. Cats will most often become aggressive when conflict is over a survival resource (including territory) or when escape from conflict is impossible; such as when the animal is debilitated or confined. However, if a cat has repeated experience of sustained threat or punishment when it attempts to escape, then it may learn to shift to an offensive pattern of aggression instead of escape. Aggression is most likely to be sustained when a cat is defending territory from an intruder.
Aggressive Sequence
The feline aggressive sequence shares some similarities with other species; non-specific increases in body tension and threatening eye contact for example. In addition there is a range of feline aggressive displays which involve whole body and facial components. The cat may attempt to present itself as as an active threat by increasing its apparent stature (piloerection, sideways body arched posture), or it may attempt to reduce the threat it poses by flattening onto the ground and adopting a self-defensive posture. These whole body postures are a reliable indicator of the cat’s attitude to a situation but they are relatively static and do not indicate the moment-by-moment shift in the cat’s reaction. For this it is better to look at facial signals such as head and ear position, and other expressions involving the mouth and eyes.
One very important point is that the transition from a static defensive posture to an attack may be very sudden in cats. It is therefore very important to be able to read and appropriately respond to changes in facial signalling that indicate the cat’s increasing sense of vulnerability which may precede an aggressive outburst.
Important warning signs include:
- Tail twitching
- Flattening of the ears
- Stiffening of the shoulders and legs
- Dilatation of pupils
- Hissing and spitting
It is very important that owners do not attempt to soothe or calm the cat when it is showing this behaviour. Cats that are frozen in a self-defensive crouch are very close to launching an attack when provoked. They should look away from the cat and slowly move away.
Classification
Aggression is a normal feature of the feline behavioural repertoire and the term ‘aggressive’ should not be used to define a cat’s personality; all cats have the capacity to display aggressive behaviour, dependent on circumstances. There have been various attempts to categorise forms of feline aggression, but without any common agreement. The most appropriate approach is to characterise the behaviour according to its objective, and emotional motivation, such as fear, anxiety, or frustration. Then to identify the targets of aggression (such as people or animals), including the specific details of high probability targets (such as age, or appearance). Aggression may be linked to context and triggering events or stimuli, which also need to be detailed in the history. By identifying motivation, target and eliciting circumstances it is not only possible to classify aggression but also make meaningful predictions about risk and prognosis.
History Taking
Inter-cat aggression presents a particular problem because many of the aggressive incidents are not directly observed by the owner or may be misinterpreted when they are. Observation of the cat during the consultation is unlikely to be useful, and a house visit is more approbate as this also enables an assessment of the living conditions of the animal. Consultations can also be augmented with video footage of the cat’s normal behaviour in its own surroundings, but it is not acceptable for clients to stage aggressive events for the purpose of making a diagnosis since this involves a serious risk of injury.
Important Aspects of History Taking
- Historical description of aggressive incidents (starting with the first that the owner can remember). Details of each incident should include location, persons/animals present, context, time, and target of the aggression.
- The cat’s body posture and facial expression before, during, and after each incident give strong indications of its emotional state and intent.
- The victim’s response before, during, and after each event should be recorded.
- Relationship between cat and other animals in the household (allorubbing, allogrooming, play, aggression, fear-avoidance).
- List of all situations in which low level aggression behaviour is seen (hissing, spitting, growling, eye contact, body posture).
- List of stimuli/events that elicit fear or anxiety.
- Contexts in which aggression is seen.
Feline Aggression Studies
Better title needed. Not sure whether below is too UK biased.
Within the general feline population house soiling and spraying are considered to be amongst the most common major problems, with aggression featuring far less than it does in the dog. However, recent figures from the annual report (2003) of the Association of Pet Behaviour Counsellors (APBC) showed that 23% of referred feline cases involved aggression towards other cats, making it the second most commonly referred problem after indoor marking (25% of cases). A further 13% of the reported feline cases involved aggression towards people. Aggression is therefore a significant concern for many cat owners. Data on referral rates of feline aggression cases to individual behavioural clinics varies widely, with some clinics experiencing referral rates of 13% of their total caseload and others 25%.
Other work, carried out by a research team at Southampton University, has shown that 13% of owners reported aggression to people and 48% aggression to other cats. These figures were obtained directly from a sample of the general cat owning population, rather than those seeking professional help and they indicate that aggression problems may be even more prevalent in the general feline population than in the referral population.
There may be many reasons for this difference. Firstly, many cat owners may be unaware of the welfare and safety risks associated with aggression problems. Secondly, the owners of aggressive cats have the option to exclude these animals from the domestic home so that they become ‘outdoor’ cats. Thirdly, and most importantly, many cat owners may not be aware that anything can be done to help the situation and therefore do not seek help. Such obstacles to seeking advice place an additional demand on the veterinary practice to ask questions about feline behavioural problems during routine consultations rather than to expect clients to raise the subject themselves.
Feline aggression is also often regarded as less serious than canine aggression, and as a consequence cases may not be referred until they have become serious. Unfortunately such an approach is not only detrimental to prognosis but also increases the risk of injury, so it is important for owners to understand how serious the consequences of feline aggression can be. Physical injury to people or animals and zoonotic infections are a very real danger since the cat is equipped with weapons in the form of claws and teeth. When feline aggression is targeted toward people, the danger it poses should never be underestimated. When the victims are children or elderly people with frail skin it is important to emphasise to owners that the potential injuries from cats are serious. The rate of bacterial contamination in cat bites is several times that in the dog, because bite punctures tend to be deep and a majority of cats harbour Pasteurella multocida and other pathogens in their mouths. Only 25% of dog bites contain Pasteurella multocida, compared to 50-74% of cat bites. Other bacteria may also be present, including Staphylococcus aureus. This means that all cat bites that cause skin penetration or bleeding should be treated medically without delay. A course of antibiotics and anti-tetanus may be required.
