One of the most useful tools when investigating a problem of feline house soiling is a plan of the house in which the cat lives. This does not need to be a detailed scale drawing but rather a basic plan indicating the layout of rooms in the house, the position of windows, doors and major furniture and the location of major resources such as feeding and watering stations, sleeping locations and play areas. Each individual cat’s favourite resting places and rooms they prefer to inhabit should be noted on the diagram. The client should mark onto this diagram the location of urine and faeces that they have found. ''[see figure]''
One of the most useful tools when investigating a problem of feline house soiling is a plan of the house in which the cat lives. This does not need to be a detailed scale drawing but rather a basic plan indicating the layout of rooms in the house, the position of windows, doors and major furniture and the location of major resources such as feeding and watering stations, sleeping locations and play areas. Each individual cat’s favourite resting places and rooms they prefer to inhabit should be noted on the diagram. The client should mark onto this diagram the location of urine and faeces that they have found. ''[see figure]''
To give a better indication of the development of the problem, the client should note the current frequency of urine/faecal deposition at a particular site, as well as how early in the development of the problem urine or faeces were first found there. A convenient way to do this is to label each location on the diagram with a number of stars to indicate current frequency and a number that indicates whether that spot was one of the first, or last places to be
soiled, or somewhere in between. The clinician may use this diagram ''[see example]'' as a basis for recording additional information about each mark, such as the volume of urine at a site, where precisely on furniture or decorations it is located and whether any particular event appears connected to it.
The pattern of urine and faecal deposits can point to the source of the problem. For example, if the first deposits were found close to doors and windows, it is suggestive that the perceived threat was coming from outside the home whilst initial deposits in the centre of rooms or onto new pieces of furniture would suggest that the disruption of the cat’s security was coming
from within the household.
Once all of this information has been collected, it is then possible to make judgements about the nature of the problem, whether it is a matter of '''indoor marking or elimination''' and what the motivation may be.
==Differentiating Between Elimination and Marking==
Once full information has been collected about the location and characteristics of each urine or faecal deposit, it is possible to differentiate between its cause.
===Positioning of Deposits and Reaction to the Litter Tray===
In the case of [[marking]], the areas that the cat uses to deposit urine or faeces will often be of behavioural significance, for example areas that smell of the owner or of the new cat in the household or locations which are associated with potential threat from the outside world. There is often a provoking stimulus for this inappropriate behaviour such as some disruption to the home environment or competition within the local neighbourhood and the location of the marking deposits will reflect this. Urine or faecal marks are placed strategically in order to provide a signal to other cats, which means that they must be placed in locations that are likely to be noticed. The act of [[spraying]] itself also involves an element of [[visual display]]. It should be remembered that odour marks are not merely of use to the ‘sender’ of the signal, who is trying
to maintain distance from other cats. They are also of use to the ‘receiver’, who is equally keen to avoid direct physical conflict. The location of scent marks therefore follows conventions that allow other cats to find and investigate them easily. Such places might include on door frames, or on doors, or on pieces of furniture that face doors or windows.
[[Inappropriate indoor elimination]], on the other hand, will usually take place in quiet secluded locations which reflect the sort of places which cats would naturally choose to use as latrines. It is also likely that elimination sites will have certain common characteristics in terms of the substrate that is used and cats will often develop preferences for the inappropriate substrate, such as carpet or linen, and return to similar surfaces repeatedly. These inappropriate substrates may be similar to those the cat was forced to use as a kitten, through an inadequate provision of proper latrines in the rearing environment.
One useful difference between indoor ‘markers’ and ‘toileters’ is their reaction to the indoor latrine facilities, with ‘markers’ often continuing to use the litter tray and ‘toileters’ actively avoiding the facilities provided. Indeed, in cases of a lack of, or a breakdown of house-training, signs of aversion to the litter tray may be the first thing that the owner notices.
Cats with [[lower urinary tract disease]] will often use several different sites in the house during the same period, breaking the usual pattern of the cat using only one or two latrines. This is because pain associated with micturition in each of the latrine sites discourages repeated use of the same locations. The cat associates eliminating in that place with pain or dysuria and chooses somewhere else next time. Amounts of urine found at each site may be smaller
then normal and have a strong odour or contain blood. This pattern of urination is often cyclical, with cats eliminating normally for a few weeks and then suffering another bout of generalised housesoiling. This fits with the cyclical nature of the severity of lower urinary tract disease, which may wax and wane.
===Frequency of Deposits===
If a cat is depositing urine and faeces, as part of the normal function of elimination, the frequency will reflect this and deposits will be limited in their number. However, when cats are using the deposits as a form of marking there is no limit on the frequency of deposition and it is not unusual for a urine spraying cat to leave in excess of thirty marks within the home in a 24-hour period.
===Volume of Deposits===
The amount of urine that is deposited can also help to determine the motivation for the behaviour with toileting problems usually involving larger quantities than [[marking]] problems. However, this can be confusing since a small amount of urine can be absorbed by carpets and other fabrics and the size of the moist patch on the floor can be misleading! Cats with FLUTD will pass many
small quantities of urine in several sites, causing confusion with a marking problem. Likewise, cats with chronic diarrhoea. However, the choice of location will still fit with normal defaecation or urination.
===Posture of Cat and Orientation of Deposits===
The posture of the cat can help in the differentiation process, since [[indoor urine spraying]] is usually associated with a characteristic stance. This is related to the function of the marking behaviour since a standing posture allows the cat to deposit urine on a vertical surface at just the correct height for another cat to sniff at it and take in the important information.
However, urine marking does not exclusively occur from a standing posture and it can be performed from a squatting position, which closely resembles the posture adopted during the act of elimination. This fact must be borne in mind when attempting to differentiate between motivations as it is easy to dismiss squatting urination on horizontal surfaces as always being eliminative and yet there are occasions when the cat is actually using that sort of urination as a
marking behaviour.
===Pattern of Urine and Faeces Deposition [identified using a house plan]===
''Certain patterns are classic indicators of a specific underlying motivation. For example, if the first urine marking deposits were found close to external doors and windows it is suggestive that the perceived threat was coming from outside the home, whilst initial deposits in the centre of rooms, corridors or staircases, or onto new pieces of furniture would suggest that the disruption of the cat’s security was coming from within the household.'' As a situation progresses, the pattern becomes more confusing so that it becomes very difficult to identify the originating cause unless the historical development of the pattern of the marking or elimination is known. For example, urine marking may progress from door and window areas to hallways and rooms if a neighbourhood despot begins to invade the resident cat’s home.
