Outlook: Good quality of life with treatment
Parvovirus
A highly contagious viral infection that attacks the digestive system, especially in puppies and unvaccinated dogs.
Signs: Severe vomiting, diarrhea (often bloody), lethargy, fever, loss of appetite, dehydration.
Care: Immediate veterinary treatment, hospitalization, IV fluids, and supportive care. Prevention through vaccination is critical.

Signs: Fever, lethargy, vomiting, diarrhea, increased thirst/urination, jaundice (yellowing of skin/eyes).
Care: Blood and urine testing, antibiotics, and supportive care. Vaccination is available for prevention.
Outlook: Can be life threatening, but infection risk is minimized with annual vaccination
Addison’s Disease (Hypoadrenocorticism)
A condition where the adrenal glands do not produce enough essential hormones, affecting electrolyte balance and stress response.
Signs: Lethargy, vomiting, diarrhea, poor appetite, weight loss, weakness, and sometimes collapse.
Care: Blood testing to diagnose, lifelong hormone replacement medication, and regular monitoring.
Outlook: Excellent with consistent treatment and management.

Care: Blood testing, medication/diet/radioiodine or surgery, monitoring.
Outlook: Good quality of life with treatment.
Feline Leukemia Virus (FeLV)
A contagious viral infection that weakens the immune system and can lead to anemia, infections, or certain cancers. Spread through close contact such as grooming, sharing bowls, or bite wounds. Some cats are silent carriers and can carry the virus without showing clinical symptoms. These silent carriers can infect other animals and spread the virus.
Signs: Weight loss, poor appetite, fever, lethargy, pale gums, recurrent infections.
Care: Simple in house blood testing for diagnosis, supportive care, management of secondary infections, and vaccination for prevention.
Outlook: Varies by cat; some live comfortably for years with monitoring and care.

Care: Emergency veterinary treatment to relieve the blockage, hospitalization, and follow-up care.
Outlook: Can be fatal if not treated quickly. Can be a life-long chronic issue, and cats with this chronic issue will likely need to be on a special diet to reduce chance of reoccurrence.
Feline Immunodeficiency Virus (FIV)
A contagious viral infection that weakens the immune system and reduces the ability to fight infections.
Signs: Often none at first; later may include weight loss, fever, dental disease, and recurrent infections.
Care: Blood testing for diagnosis, routine wellness care, and prompt treatment of infections.
Outlook: Many cats live long, comfortable lives with proper care.
