The majority of behavioural cases presented in veterinary practice are related to normal feline behaviour that is expressed in an inappropriate or undesirable manner.

Physical health

It is important to be aware that health problems are a common causal or underlying factor in behavioural problems in cats. For example, lower urinary tract disease (FLUTD) and housesoiling and indoor urine marking are commonly linked. A full physical and clinical examination should be completed before any type of behavioural therapy is implemented. Behavioural changes may precede clinical signs, and also persist after an illness is apparently resolved.

The main ways in which health problems can affect behaviour include:

  • Altered motivation: Polyphagia and polydipsia (e.g. due to diabetes mellitus or hyperthyroidism) can lead to competition over resources, pain can cause increased defensive behaviour
  • Altered perception or cognition: Decreased awareness of signalling can lead to interact conflict (e.g. visual impairment), and cognitive dysfunction can lead to confusion, anxiety and irritability. Focal epilepsy can produce confusion, sensory disturbances and mood changes.
  • General response to illness: Inflammatory cytokines activate a pattern of decreased activity, social withdrawal and avoidance that is called sickness behaviour (due to the effect of inflammatory cystokines).

Additionally, high levels of stress can cause alterations in behavioural, physiological and immune responses. Stress-linked alterations in the hypothalamic-pituitary axis may be linked to effects on levels of dopamine, serotonin, noradrenaline and prolactin. In animals, stress is a contributing factor to gastrointestinal disturbances, skin conditions, feline interstitial cystitis as well as compulsive disorders and increased fear responses.

History Taking

Detailed history taking is the most important aspect of reaching a diagnosis in behavioural medicine. This should include information about:

  • The problem from the client's perspective and their expectations of treatment.
  • Individual cats (origin, development, influential experiences, personality traits, history of sociability with other cats and people, current and past health, current and past drug treatments).
  • The physical environment (including resource availability and distribution, opportunities to perform normal behaviour and avoidance and escape responses).
  • Important changes; for example the introduction of a cat, arrival of a new baby, house move, building work, or a change of owner employment/health.
  • The social environment (relationship with other resident cats, people and other animals).
  • The relationship with the owner.
  • Methods of treatment already used by the owner (including punishment)
  • The owner's level of knowledge of normal cat behaviour
  • Detailed description of specific events (including context, triggering events/stimuli, and the individual's response).


It is also often helpful to place key information onto a timeline, as this can make it easier to visualise the connnection between events in the cat's life. Prognosis is considerably affected by owner expectation; it may not be possible to achieve complete harmony between a group of cats, but if this is the only acceptable outcome for an owner then the prognosis will be poor. Historical information and observation may be supplemented with videos or visits to the animals normal environment.

Social Structure within the Home

If more than one cat resides within the same home, it is important to establish their relationship. An interaction, similar to the one in the figure 1., can be used to show the pattern of interaction between cats. During the consultation, the clinician questions the owner about a range of affiliative and aggressive behaviours, and annotates the diagram.

  • Friendly: e.g. grooming, rubbing against, tail-up greeting
  • Aggressive: e.g. chasing, growling, hissing, spitting, fighting

It is possible to have no affiliative behaviour at all between members of a group of cats, or a to find that there is a a cohesive group with single outsider. Factions are also often found to exist with a household. Understanding the social relationships between cats provides a basis for resource distribution, reduce inter-cat conflict and and finding ways to re-integrate the group.

Resource availability and distribution

The correct distribution and availability of resources is critical to preventing and treating inter-cat conflict.

House Layout

Draw a diagram of the house to show where the cats have food, water, litter trays and cat flap (similar to the figure 2. image). Also mark on this where urine or faeces have been found and which cat left them, if relevant. This is particularly important in cases of housesoiling but is useful in other cases too as it helps to establish the appropriate allocation of resources.

Feeding

Find out which type of food is the cat fed (dried, moist etc) and how many times a day or whether food is available for thee cats at all times. Do the cats often leave food after each meal?

Outdoor Access

Information about access to the outdoors also plays a vital part of a feline behavioural consultation. The main question is whether the cat has any outdoor access at all, then to what extent and whether it can control its own access. The questions asked should be similar to: Can the cats go outdoors? Does the owner have to let them in and out? Is there a cat flap? If so, is it open at all times? Is it an electronic/magnetic coded one? Do the cats have other ways in and out of the house [windows etc]? Are any of the cats reluctant to go out? Is there a reason the owner is aware of why they won’t go out? Do any of the cats go to the toilet in the garden?

More detailed information is then obtained depending on the main problem:
