SSRI Use in Cats

SSRIs or Selective Serotonin Reuptake Inhibitors are drugs used to affect behavior. In recent years these drugs have been used to modify behavior in cats and other small animals. As indicated, SSRI's affect serotonin levels in the brain and central nervous system. Fluoxetine is an SSRI often used for cats.

  1. History

    • SSRIs were originally marketed for humans under the name "Prozac." Other names for these drugs are Flurozin, Sertraline and many others.

    SSRI Use for Cats

    • SSSRI's are used to treat the following conditions in cats:
      - timidity or excessive fear
      - urination and litter box problems
      - aggression and compulsive behavior.

      Obsessive-compulsive behavior in cats may include constant licking, picking or pulling out fur.

    Results -What to Expect

    • Cats should take SSRI medication continuously for it to be effective. Experts say that it will take from four to six weeks until medication begins to affect conditions. SSRIs should be used a minimum of four months before the pet owner decides if their cat should continue on the medication. Cat owners should expect 1 to 4 weeks before medication takes affect. SSRI's can improve the cat's behavior, making them more playful and relaxed.

    Negative Effects in Cats

    • Cat owners should be aware that on rare occasions SSRIs may cause aggressive behavior in cats. Other potential side affects are:
      - lethargy
      - upset stomach
      - loss of appetite.
      - panting
      - restlessness

    • SSRIs are processed throught the liver and kidneys. Cats should have a blood test before use. SSRIs should not be used with MAOIs, and extreme caution should be given to cats taking SSRIs with other medications. Cats suffering from diabetes or seizure disorders are usually not prescribed Fluoxetine. Overdose affects may appear within one hour. Symptoms include hyper-salivation, lethargy and seizures.
