FELINE PANLEUCOPENIA CLINICAL SIGNS
The severity of the disease varies considerably in susceptible individuals,
from either a subclinical infection, to a mild transient fever and leucopenia, to
a severe, peracute syndrome where the cat may be found dead. In general, the disease
tends to be more severe in young kittens.
The following signs are, however, often typical:
Incubation period 2-10 days.
First signs of illness are lethargy, fever, anorexia, and apparent
thirst but refusal to drink.
Vomiting generally occurs.
Diarrhoea less common, particularly in early stages.
Abdominal palpation reveals fluid-and-gas-filled intestines, and
may elicit pain.
After 2-3 days, symptoms variable, e.g. fever, profuse watery diarrhoea
or dysentery, severe dehydration and electrolyte imbalance.
Anaemia not usually present though may develop in long-standing
cases especially if there is intestinal bleeding.
Subnormal temperature carries grave prognosis.
Mortality rate varies from 25% to 75%.
Fatalities due to overwhelming bacterial infection, dehydration,
and electrolyte imbalance.
