Feline upper respiratory tract infections (URIs), also termed as feline infectious respiratory disease or feline upper respiratory disease complex (URD), are common ailments in cats, caused by a variety of viral or bacterial agents. Similar to a common cold in humans, these infections can manifest with a range of severity, sometimes even life-threatening, and necessitate vigilant care and management to ensure the well-being of the afflicted feline.

CAUSE
The predominant causative agents of feline URIs are the feline herpesvirus type 1 and feline calicivirus, which together account for about 90% of such infections. Other bacteria like Bordetella bronchiseptica and Chlamydophila felis also play a role in the etiology of these infections. It's noteworthy that a cat may be infected with more than one agent, making the management of the condition slightly complex.

SIGNS
The symptoms indicative of a URI include:

• Clear or colored discharge from the eyes or nose

• Coughing and sneezing

• Swelling of the mucous membranes around the eyes (conjunctivitis)

• Mouth ulcers

• Lethargy and anorexia

• In rare instances, difficulty in breathing

The manifestation of these symptoms can be mild to severe, and may resemble other feline diseases, thus necessitating a thorough examination for accurate diagnosis.

DIAGNOSIS
Diagnosis begins with a detailed medical history and thorough physical exam. Often, this can provide enough information to make a relatively confident diagnosis. Individual cases may require further diagnostic tests like X-rays, blood tests, or bacterial cultures to aid in identifying the causative agents and the extent of infection.

TREATMENT
The treatment of feline URIs often hinges on supportive care, especially if a viral infection is suspected. This is very case-dependent but we often recommend some combination of the following:

• Probiotics or supplements to bolster the cat’s immune system

• Antiviral or antibacterial medications

• Symptomatic treatment for relief from coughing, sneezing, or fever

It's pivotal to follow the treatment plan devised by the veterinarian, and ensure a clean, stress-free environment for the cat to recuperate.

PROGNOSIS
The prognosis for cats with URIs is typically very good, especially with timely and appropriate treatment. However, the severity and frequency of symptoms can vary significantly from one cat to another. Ensuring regular veterinary check-ups, adhering to the treatment regimen, and maintaining a hygienic living environment for the cat are crucial steps towards managing this condition and enhancing the quality of life for the affected feline.

PREVENTION
Preventative measures are pivotal to reducing the risk of occurrence or recurrence of symptoms. At YVC we believe these measures (and others) are critical to keeping your pet happy and healthy:

• Vaccination against common causative agents

• Keeping indoor cats away from potentially infected outdoor cats

• Regular cleaning and disinfection of living spaces

• Providing a balanced diet to support immune health

Feline upper respiratory tract infections are manageable conditions with a multifaceted approach involving accurate diagnosis, targeted treatment, and vigilant preventative measures. Through collaborative effort between pet owners and veterinarians, the impact of URIs on our feline companions can be significantly mitigated, ensuring their long-term health and happiness.
