Common Diseases In Stray Cats
Stray cats often carry diseases that can affect other animals and humans. These diseases spread through bites, scratches, or contact with bodily fluids.
Knowing about these illnesses helps protect you and your pets. Here are some common diseases found in stray cats.
Feline Leukemia Virus (felv)
FeLV is a virus that weakens a cat’s immune system. It spreads through saliva, blood, and close contact. Infected cats may show weight loss, fever, or pale gums. The virus lowers their ability to fight other infections.
Feline Immunodeficiency Virus (fiv)
FIV works like HIV in humans. It attacks the cat’s immune system over time. Cats with FIV may not look sick at first but can get infections easily. The virus passes mainly through bites from infected cats.
Toxoplasmosis
Toxoplasmosis is caused by a parasite called Toxoplasma gondii. Cats get it by eating infected animals. People can catch it from cat feces or contaminated food. It can cause flu-like symptoms or serious problems in pregnant women.
Cat Scratch Disease

- Fever and chills
- Swollen lymph nodes near the scratch

- Skin rash or red bumps
Rabies
Rabies is a deadly virus that affects the brain. It spreads through bites from infected animals. Stray cats can carry rabies if they are not vaccinated. Early signs include changes in behavior and weakness.
