COVID-19 is a disease caused by the coronavirus SARS-CoV-2. Current evidence suggests that person-to-person spread is the main source of infection. While there is evidence of transmission from humans to dogs and cats, it does not appear common. If you suspect that you are ill with COVID-19, you should take the same precautions with your pet as you would with people.

Diarrhea is a symptom of an underlying problem that may be minor or very serious. Some cases may resolve on their own or with minimal treatment, while other cases require in-depth diagnostic testing and more aggressive treatment to address the underlying condition. The possible causes, diagnostic tests, and treatment protocols for diarrhea in cats are numerous and they are explained in this handout.

Echinococcosis refers to being infected with a tapeworm of the genus Echinococcus and is primarily a parasite of coyotes and foxes. Infected cats are usually asymptomatic, but in both cats and humans the parasite can cause large cysts to form within the lungs and liver. E.multilocularis is treated with praziquantel and in most cases the prognosis is good.

Giardiasis is an intestinal infection caused by a microscopic protozoan. The parasites attach themselves to the intestinal wall and the damage causes an acute, sudden onset of foul-smelling diarrhea. Diagnosis may be by routine fecal flotation or presumptively based on clinical signs. Fenbendazole and metronidazole are the drugs most commonly used to kill Giardia. Giardiasis is the most common intestinal parasitic infection of man and can potentially be passed from cats to humans.

Feline viral rhinotracheitis (FVR) is an infectious disease caused by feline herpesvirus type-1. It is a major cause of upper respiratory disease in cats and is the most common cause of conjunctivitis. The typical symptoms of FVR involve the nose, throat, and eyes, and include sneezing, nasal congestion, conjunctivitis, excessive blinking, squinting, and discharges from the eyes and nose that range from clear and watery to thick and purulent (containing yellow/green pus). Treatment consists of supportive care, hydration of the environment, and control of secondary bacterial infections with antibiotics and antibiotic eye medications. An effective vaccine exists and is recommended for all cats.
-
Hookworm is a parasitic infection of the gastrointestinal tract of cats. Their name is derived from the hook-like mouthparts they use to anchor themselves to the lining of the intestinal wall. How the infection is spread along with clinical signs, diagnosis, treatment, and prevention are covered in this handout.
-
Vaccinations are important to prevent serious illness in cats. Even cats that spend all their time indoors should be vaccinated. Some viruses can be carried into your home on inanimate objects such as shoes and clothing, therefore infecting your cat without her coming into contact with another animal. Your veterinarian is your most important resource in determining what vaccinations you need to give your cat to keep her protected.

This handout outlines common internal parasites in cats. Included are parasites of the gastrointestinal tract (roundworms, hookworms, and tapeworms), as well as parasites of the circulatory system (heartworms). How each of these parasites can affect your cat and what you can do to prevent or treat infection are explained.

In North America, many parasitic lungworms infect cats. Cats can become infected by swallowing infective stages of parasitic lungworm. The exact means of becoming infected varies according to the life cycle of the particular parasite. Signs can include coughing, heavy breathing, wheezing, sneezing, poor appetite or anorexia, weight loss, fever, enlarged lymph nodes, and ocular or nasal discharge, and may be more prominent in kittens due to their immature immune systems. Although the success rate of treatment depends on the severity of symptoms and the number of parasites present, the prognosis for recovery is generally good.

The Ebola virus is very contagious and is transmitted through blood, body fluids, and tissues, but not through air, water, or food. Ebola affects humans, non-human primates, and is carried by fruit bats. Other species do not appear to be affected, although there has been evidence of exposure to the disease in dogs, cats, and other domestic animals. Domestic animals are not believed to transmit the virus; however, there is a risk that they could transmit body fluids such as saliva on their fur to other humans. Any potential exposure to Ebola should be reported to your veterinarian who will contact the Center for Disease Control (CDC).
