Cats + Emergencies

  • 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.

  • 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.

  • 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.

  • Bladder stones are rock-like formations of minerals that develop in the urinary bladder. All stones form because of disease or inflammation in the bladder. The most common signs of bladder stones in the cat are blood in the urine and straining to urinate. Large stones may act almost like a valve, causing an "on-off" or partial obstruction at the neck of the bladder. In males, small stones become lodged in the urethra and cause an obstruction. X-rays (with or without contrast dyes) or ultrasound may be necessary for diagnosis. The fastest way to remove bladder stones is via a surgical procedure called a cystotomy. Special diets or passing a catheter may be successful for some bladder stones. Your veterinarian will advise you of the best course of action for your cat’s particular situation.

  • This handout summarizes the possible reactions a cat may experience when receiving a blood transfusion. Many transfusion reactions occur acutely, within seconds of starting the transfusion up to 48 hours post-transfusion. The clinical signs and treatment protocols both vary based on the type of reaction. Prior to a blood transfusion, your veterinarian may perform tests to help ensure that the donor blood is a good match for your cat.

  • Cats are exposed to botulism by eating raw meat or dead animals containing botulinum toxin produced by Clostridium botulinum. Botulism causes ascending paralysis of the nervous system. Clinical signs are reviewed as well as diagnostic tests and treatment. Prognosis is guarded depending on the amount of toxin ingested and the degree of supportive care available. There is no vaccine.

  • Brain injuries are devastating and, unfortunately, often fatal. The typical signs of brain injury in a cat include altered consciousness that may signal bleeding in the skull, decreased blood flow to the brain, or fluid causing swelling within the brain itself. There are many potential causes of brain injury and treatment will always be determined by the underlying problem that led to the injury.

  • Bromethalin is a common rodenticide. Cats are commonly poisoned when they find loose bait placed for rodent control. Relay toxicity, where poisoning occurs due to ingesting rodents that died from bromethalin, has been anecdotally reported in cats. Clinical signs can develop as soon as two hours after exposure and as long as 24-48 hours after exposure. There is no antidote for bromethalin, so prompt induction of vomiting by a veterinarian can be lifesaving. Prognosis is poor to grave if severe clinical signs develop such as seizures, paralysis, or coma. Patients with milder clinical signs may recover after several weeks but may have permanent neurologic damage.

  • A burn is a type of skin injury, commonly caused by heat, fire, or chemicals. Burns are classified based on how many layers of skin are affected; this classification scheme can help predict prognosis. Treatment of burns varies, depending on the severity of the burn and how much of the body is affected. Superficial burns may heal without treatment, while more severe burns may require hospitalization and possible skin grafts.

  • Cats and dogs can become intoxicated by cannabis in various ways, most commonly by eating edibles (e.g., baked goods, candies, chocolate bars, and chips containing cannabis), or by ingesting cannabis directly (in any form). Pets can also be exposed to second-hand smoke. A small amount may affect one pet more than another, so there is no official safe level of exposure. Many of the signs of intoxication are neurological, including disorientation, dilated pupils, and hyperactivity. In severe cases, tremors, seizures, and coma can result. Regardless of the method of exposure, accurate and complete information from the owner is imperative to treat the patient successfully.
