In part 1 of this article we looked at the difference between urine marking and inappropriate elimination in cats, and urine marking was discussed in more depth. In this article we will look at the reasons for inappropriate elimination as well as the diagnosis and treatment of both inappropriate elimination and urine marking.
In order to understand disease of the urinary system it is important to understand the anatomy of this system. The urinary system comprises two kidneys which are linked to the bladder by two tiny tubes called the ureters. The ureters terminate in the lower part of the bladder commonly referred to as the neck of the bladder. The bladder is a balloon like structure which can expand to many times its empty size when it is filled with urine. The main tube taking urine from the bladder to the genital organs is called the urethra. The urethra terminates in the vagina in female and in the penis in males.
- If the cat is not yet sterilised it will usually be the first treatment to be recommended. Urine marking, especially in male cats, is a testosterone-driven instinct. Once the testicles have been removed and the production of testosterone is curbed, the urge to mark, dominate and defend a territory is substantially reduced.
- Decrease social stress between cats in the household by ensuring that there are enough resources (food and water) available to all of them, placed in different locations.
- Ensure all cats have a safe place where they can hide from one another.
- Have at least one litter box per cat plus an extra one in different areas of the house.
- Clean litter every day and change it once a week.
- Spend quality time with each cat on a daily basis.
- Do not clean the area that is marked with solutions containing ammonia and/or chlorine.
- Discourage stray cats from entering your property.
- Restrict visual access into and out of the home.
- Do not punish the cat that is marking, it will just increase the anxiety.
- Pheromones can be used in the form of a diffuser spray or collar to increase the cat’s sense of safety and contentment within the home and;
- as a last resort behaviour modification drugs (antidepressant drugs) can be used. These drugs are however not registered for use in cats in South Africa and can therefore only be used “extra-label” where you have to consent to the use the medication to treat your cat.
- Surgery.
- Dietary adjustments both in terms of water or fluid intake (some cats prefer running water vs. water in a bowl) as well as the type of cat food being fed e.g. wet (tins or pouches) vs. dry (kibbles or pellets). In many cases, the vet may prescribe a veterinary prescription diet which may have to be changed in the short term, or alternatively which your cat will have to stay on for the rest of its life.
- Medicines both scheduled and non-scheduled.
- Pheromone therapy.
- Pain relief – some cats might need occasional pain relief if they suffer from recurrent idiopathic cystitis. (WARNING: Do not use human pain relief medications in cats. Some over the counter medications like Paracetamol are highly toxic to cats and will most certainly kill your cat.)
- Neutroceutical supplementation – some cats have shown positive responses to glycosaminoglycans (GAG) and/or Omega3 Fatty Acid supplementation. (In humans it has been shown to exert a protective and anti-inflammatory effect in the human bladder and kidneys, but comprehensive studies have not been conducted in cats.)
- Behaviour modification drugs.
