Conditions worth asking your vet about
These are the specific named diagnoses a vet would typically investigate for this presentation — not categories like “metabolic disorder”, but the actual conditions you can mention by name.
Feline herpesvirus (FHV-1)
Feline herpesvirus is a common cause of upper respiratory infections in cats, especially kittens. It often presents with sneezing, nasal discharge, and eye issues like conjunctivitis or crusty discharge. Diagnosis is typically based on clinical signs and PCR testing.
Feline calicivirus
Feline calicivirus is another viral cause of upper respiratory infections in cats, characterized by sneezing, nasal discharge, and sometimes oral ulcers. Kittens are particularly susceptible. Diagnosis is often made through PCR testing or viral isolation.
Chlamydophila felis
Chlamydophila felis is a bacterial infection that primarily affects the eyes, causing conjunctivitis and discharge. It can also cause mild respiratory symptoms like sneezing. Diagnosis is confirmed through PCR testing or culture.
Mycoplasma felis
Mycoplasma felis is a bacterial pathogen that can cause conjunctivitis and respiratory symptoms in cats. It often presents with eye discharge and sneezing. Diagnosis is typically made via PCR testing.
Bordetella bronchiseptica
Bordetella bronchiseptica is a bacterial infection that can cause respiratory symptoms in cats, including sneezing and nasal discharge. It is more common in environments with high animal density. Diagnosis is confirmed through culture or PCR testing.
Feline infectious peritonitis (FIP)
FIP is a serious viral disease caused by a mutated coronavirus. While it primarily causes systemic symptoms, early signs can include respiratory symptoms like sneezing and nasal discharge. Diagnosis is complex and often involves ruling out other conditions.
Easily confused with: Allergic rhinitis · Foreign body in nasal passage · Fungal infection (Aspergillosis) · Nasopharyngeal polyp

Bilateral conjunctival sporotrichosis in a domestic cat: case reportFrontiers in Veterinary Science · 2025 · CH
A 2-month-old mixed-breed kitten in Brazil was diagnosed with a rare eye infection called sporotrichosis, caused by a type of fungus. The kitten had red, swollen eyes with a lot of discharge and some unusual growths on the eyelids. To figure out what was wrong, the vet ran several tests, including blood work and cultures, which confirmed the presence of the fungus. The kitten was treated with eye drops and oral medication, along with some supplements to help with healing. After four months of treatment, the eye lesions cleared up, although there was some minor scarring left.

Coinfection with Clostridium piliforme and Felid herpesvirus 1 in a kitten.Journal of veterinary diagnostic investigation : official publication of the American Association of Veterinary Laboratory Diagnosticians, Inc · 2015 · United States
A 1-month-old Domestic Shorthair kitten was found to have died after experiencing symptoms like a runny nose, trouble breathing, and diarrhea. This kitten was the third from its litter to die in a month with similar issues. During the examination, the kitten had severe eye inflammation, nasal inflammation, and lung problems, which were linked to an infection with Felid herpesvirus 1. Additionally, there were signs of intestinal infection caused by a type of bacteria called Clostridium piliforme, which is known to cause a disease called Tyzzer's disease. Unfortunately, this case highlights a serious situation where the kitten had both infections, and it did not survive.

Investigation of chlamydophilosis from naturally infected cats.Journal of veterinary science · 2021 · United States
This study looked at a type of infection called chlamydophilosis in cats, which can cause eye and respiratory problems. Researchers observed three cats showing signs of this infection, especially recurring eye issues. They took samples from the cats to test for the infection and found it in both the samples and during a post-mortem exam of one cat that had died. The findings suggest that while some cats may not show symptoms, they can still carry the infection and spread it to others. It's important for pet owners to be aware of this disease and seek proper treatment to prevent ongoing health issues and costs.
