What is pica?The word pica comes from the Latin word "magpie", which is known to eat almost anything. Pica in cats is a potentially serious condition where they have an abnormal compulsion to eat non food substances such as clothing, plastic, wood etc. Pica is more often thought of as a condition of pregnant women, who occasionally have cravings (and indulge in them) for non food items such as chalk, dirt etc. However, pica isn't exclusive to pregnant women & it is seen in non pregnant humans & also animals. What about wool sucking?Wool sucking is well known among cat lovers. As the name suggests, it involves the cat (usually Siamese or Siamese mix) sucking & eating wool or other clothing items. What are the causes of pica?- There is no firm answer to this question, but several theories have been suggested;
- Dietary insufficiencies, and possibly needing more fibre, minerals or vitamins in their diet.
- Wool sucking may be a result of a cat being weaned too early, and takes to this as a self soothing mechanism.
- Stress & anxiety.
- Boredom.
- Wool sucking is seen more commonly in Siamese & Siamese cross breeds, which suggests that there may be a genetic component to this behavior.
Is pica dangerous?It can be. It could lead to poisoning for instance or if a large volume of something is eaten & can't be easily digested it could lead to an intestinal blockage. If your cat stops eating, vomits has diarrhea or becomes lethargic contact your veterinarian immediately. What can be done to stop this behavior?It is important to take any cat displaying signs of pica to your veterinarian for a thorough physical examination to rule out a medical problem. Your veterinarian may wish to do a complete blood profile to check iron levels, hormone levels, check organ function etc. If no illness or disease is diagnosed you may try the following; - It is quite common for cats to chew on plants, however it can prove fatal if the wrong plant is eaten. I'm not completely sure that plant eating could be entirely classified as pica as it is quite commonly seen in cats. There is no concrete explanation for this but some suggestions include, plants contain certain nutrients which are not available in it's regular food, ingestion of plants assists in bringing up hairballs. If your cat has been chewing on the houseplants the simplest solution is to remove them from your cat's reach & replace with cat friendly plants such as catnip or cat grass.
- Feed your cat a well balanced & good quality diet. A high fibre diet has been found to eliminate this behaviour in some cats. Speak to your veterinarian before making any changes to your cat's diet. Also, a constant supply of dry food may be of help.
- If your cat is chewing clothing, remove this from your cat's reach. Make sure clothing is put away in cupboards & drawers where you cat can't access them.
- Providing your cat with alternative objects to chew on such as raw (never cooked) bones with some meat still attached.
- If the targeted item is something you can't put away easily, such as electrical cords it may be necessary to paint them with something to deter your cat from chewing them, such as bitter apple or Tabasco sauce.
- Reducing stress. Onset of this behavior is sometimes triggered by stress. It has been mentioned that pica often occurs in adolescence & may begin when a cat moves into a new home. Therefore time spent with the cat ensuring it is in as stress free an environment as possible may help. This includes introducing your new cats to other pets in the household slowly.
- Reducing boredom. The more time your cat is entertained, the less time it has to engage in inappropriate behaviors such as pica. You can try hiding more cat friendly morsels around the home for your cat to discover. A supply of interactive cat toys & a high cat tree close to a window where your cat can watch the outside world.
- Remote punishment such as using a water pistol when your cat engages in this behavior.
- If your veterinarian believes that the pica is related to a behavioral disorder which can not be easily remedied then he may recommend medication.
Sometimes this behavior will resolve itself in time.
