Behavioral health medications are used in animals and humans. They include antidepressants, atypical antidepressants, antipsychotics, and amphetamines. Dogs and cats often require lower doses of these medications than humans and are sensitive to overdoses. As such, when a dog or cat gets into human doses of these medications or a pill vial of their own medication, behavioral health medication poisoning can occur.

AIHA or IMHA is a life-threatening condition that may occur as a primary condition or secondary to another disease. Most cats with AIHA have severe anemia and their gums will be very pale. They will be anorexic, listless, easily tired, and will have increased heart and respiration rates. Diagnosis involves a complete blood count (CBC), biochemical profiles, urinalysis, and X-rays or ultrasound of the abdomen and chest. Treatment may involve blood transfusions and other medications over a prolonged time. The prognosis may be better if an underlying cause can be identified.

Atrial fibrillation describes very rapid contractions or twitching of the heart muscle, specifically in the atria. Most of the time, atrial fibrillation in cats occurs secondary to heart disease. Sometimes, in large breed cats, atrial fibrillation will occur as a primary heart problem. Most cats who develop atrial fibrillation have underlying heart disease, so the signs that are observed are often related to that underlying condition, and may include exercise intolerance, cough, or difficulty breathing. Treatment varies depending on whether the pet has primary or secondary atrial fibrillation. Your cat will need to be monitored on a regular basis.

Aspirin is a commonly used, over-the-counter, nonsteroidal anti-inflammatory drug (NSAID) and is used to treat fever, pain, swelling, and clotting disorders in humans. Aspirin poisoning occurs when a cat ingests a toxic dose of aspirin, either through misuse or accidentally. Cats are especially sensitive to aspirin and salicylates, and as a result are more vulnerable to poisoning than dogs. High doses may damage major organs like the liver, kidneys, and central nervous system.
