Why Do Adult Cats Suckle?

You might have noticed your adult cat suckling on a blanket regularly or even on your clothing and skin. Even though this behavior may seem strange, it is fairly common among felines who were separated from their mothers too soon. Adult cats often carry on this comforting habit for life but there are some measures you can take to distract your cat if the behavior becomes bothersome. If you suspect that your cat is suckling due to illness or out of compulsion, you should discuss your concerns with a veterinarian.

  1. Demonstrating Affection

    • This behavior is often a form of showing affection in cats that have been orphaned or weaned before six weeks of age. When newborn kittens suckle milk from the mother cat they purr and knead to let her know that they are content and happy. When cats get older and continue these behaviors, they are showing you that they feel secure with your mutual bond. These infantile behaviors are less likely to continue into adulthood when cats stay with their mothers and litter mates until they are between seven and twelve weeks of age. If your cat is suckling occasionally and it doesn't bother you, it is safe and appropriate to allow your cat to continue this affectionate display of trust.

    Compulsion

    • Sometimes suckling can take the form of a compulsive disorder. As with humans, a compulsive action is one that your cat feels the irresistible urge to repeat over and over again. Compulsive behaviors can become so problematic that they affect the ability of your cat to function normally. If your cat actually ingests fabric or wool while suckling repeatedly an intestinal obstruction could be the end result. Sensitive cats may begin suckling whenever they become stressed or aggravated as a form of displacement. Compulsive suckling may be reduced through a combination of drug therapy, environmental changes and behavior modification.

    Illness

    • If your adult cat hasn't suckled in the past and you have noticed regular suckling behaviors recently, you should visit your veterinarian for a checkup to rule out potential hyperthyroidism. This illness has been known to create sudden changes in behavior, including suckling. Thirty percent of all cats over the age of ten have hyperthyroidism.

    Boredom

    • Adult cats require adequate attention from their owners. They also require ample mental stimulation to feel satisfied and occupied throughout the day. If your cat is lacking in these crucial areas, boredom may be the cause of the suckling behavior. Suckling in this instance is simply a way to feel comfortable and relaxed in long periods of free time. You can try to reduce the suckling behavior by playing with your cat more often or even providing more toys for your cat to play with. Cats are actually capable of entertaining themselves in stimulating environments. Try placing a "cat tree" in the house or play some cat videos on your television when you aren't home. If you initiate active play and exercise with interactive games while you are at home, you can help your cat release stress which may deter it from suckling.
