Anxiety disorders are common in indoor cats. Signs of anxiety include aggression, elimination outside of the litter box, excessive self-grooming, and hyperactivity. Drugs commonly used as antidepressants in humans are usually prescribed to treat feline anxiety issues.
These medications affect the level of serotonin in the body. Serotonin is a neurotransmitter, a chemical that works in the brain, and is found in the nervous system. It regulates behavior, awareness of pain, appetite, movement, body temperature, and function of the heart and lungs.
If a cat is taking more than one type of medication that causes levels of serotonin to increase in the body, a condition known as serotonin syndrome (SS) can result, and if not caught in time, can lead to death.
As seen in humans, serotonin syndrome may cause:
Drugs prescribed as antidepressants in humans are becoming more common for use in animals. These medications alter the body’s levels of serotonin, and thus alter mood and behaviors. Some commonly used antidepressant drugs in cats include buspirone and fluoxetine.
Serotonin syndrome can be triggered when:
Signs of serotonin syndrome usually come on rapidly; anywhere from 10 minutes to up to four hours after ingestion.
Your veterinarian will conduct blood tests to figure out if your cat has an infection, as well as to determine what substances the cat might have eaten. Neurological testing (measuring reflexes and coordination) will be also performed to pinpoint a specific area of the nervous system that might be affected, like the brain or spinal cord. There is not a specific test that can be run to tell the veterinarian that serotonin syndrome is to blame. The history of drug ingestion and the signs your cat is showing should lead to the proper diagnosis.
