Herbal nutrition to help address symptoms of calcivirus and flu symptoms in cats and dogs. 

Cat supplements for the calcivirus infection in cats and dogs

The immune system is a complex array of cells that are found throughout the body. Immune cells are designed to function in conjunction with other cells to provide a defense against unwanted invaders. The complexity of the immune system requires a multi-dimensional approach of nutritional factors.

Calcivirus, also known as feline upper respiratory infection, is a group of bacteria and viruses that cause discharge from the nose and eyes. Feline calicivirus, along with feline rhinotracheitis (caused by herpes virus), accounts for 85 percent to 90 percent of all upper respiratory infections in cats.

Calcivirus infection symptoms typically include upper respiratory symptoms, including flu-like symptoms, pneumonia, oral ulceration and occasionally arthritis. 

Calicivirus is caused by contact with the discharge from an infected animal. Contact can be direct, spread via airborne droplets from sneezing or grooming an infected area, eating from a contaminated food bowl or using the same bedding or litter box. Feline calicivirus is most common in kittens, multi-cat households, and shelters. Many cats can be infected with the virus and remain asymptomatic, not showing any signs of illness.

Upper respiratory infections usually carry a good outcome, however, a more virulent strain of Feline Viral Respiratory disease can cause death in 60 percent of cats. Supportive care is the only treatment option, such as with herbal supplementation.

Common symptoms and signs of calicivirus include:

Discharge of the eyes

Discharge of the nose

Red eyes

Redness around eyes

Mouth ulcers


Lack of appetite (due to blocked nasal passages inhibiting the sense of smell),

Joint pain

Ulcers on paws


Rhinitis (inflammation of the nasal passages)

Ulceration of the tongue and palate.


Anorexia (loss of appetite)

Weight loss


The organs or body systems most affected include the respiratory tract, gastrointestinal system and musculoskeletal system.

Differential DiagosisFeline rhinotracheitis, bordatella bronchiseptica, Chlamydophila felis

Canine calicivirus can be implicated in cases of glossitis (inflammation of the tongue) and enteritis (inflammation of the intestine) in dogs. Diagnosis of the pathogen in the laboratory involves isolation and identification of canine calicivirus particles from feces and occasionally oral lesions.
