Signs and symptoms of FeLV
Cats usually catch FeLV through direct contact with the saliva of infected cats, through grooming or sharing food or water bowls, or through mating behaviour. There is an incubation period of months, or sometimes years, before signs of infection show in those that are infected.
Signs include recurrent infection with respiratory infections, sore gums or digestive problems. The cat might also appear 'off-colour' or have a high temperature. Enlarged lymph nodes, severe anaemia and breeding problems are also signs.
