Trembling in Cats

A trembling pet cat can be alarming, especially if the cat is normally very calm. Fortunately, most cases of trembling in felines aren't the result of a disorder. They're caused by temporary situations like fear, cold or extreme excitement. Sometimes, though, trembling is a sign of bigger problems. Learning to recognize the signs of problem trembling can help you get veterinary help in time.

  1. Causes

    • Trembling may occur for a number of different reasons. Elderly cats may tremble because of muscle weakness. Animals in pain may also tremble. Cats with digestive problems may also exhibit trembling--it's common precursor to vomiting and episodes of diarrhea, and is associated with constipation as well. Cats suffering from allergic reactions, poisoning, nutritional imbalances or metabolic disorders may also tremble.

    Prevention/Solution

    • If possible, determine the reason for the trembling behavior. If it's based on an emotional response, it will probably go away in short order. If you suspect that cold is the problem, immediately place the cat someplace warmer. If you see your cat trembling routinely or constantly, without an obvious cause, or if the trembling accompanies pain, confusion, lethargy or weakness, see a veterinarian immediately.

    Misconceptions

    • Conditions that cause trembling may occur gradually. This causes some pet owners to believe that a cat is "just nervous." Even if trembling symptoms have been present for long periods, ask your veterinarian about them. Thyroid conditions, minor seizures, electrolyte imbalances and similar problems can all cause these symptoms. Treatment of the underlying disorder will usually alleviate the trembling, reducing other behavioral and health problems, too.

    Considerations

    • New pets or rescued animals still recovering from health problems are more likely to tremble. If your new cat or kitten seems to shiver a lot in the first few days, it may not be a problem. Keep an eye on its behavior to determine whether there's a real health problem to deal with or whether your new pet is simply excited or frightened by its surroundings.

    Warning

    • Trembling may be caused by ingestion of toxic plants, insecticides and other poisons. If a previously calm cat has suddenly begun trembling and shows symptoms of illness or unusual behaviors, see your veterinarian immediately. Some poisons can do significant damage in a short period of time. Your cat needs veterinary attention as soon as possible.
