Feline Panleucopaenia
Feline panleucopaenia is a very serious disease of cats which
carries a high risk of mortality especially in young cats and
kittens. The virus is very similar to the one that causes parvovirus
in dogs and indeed recent parvovirus strains of dogs have been
show to infect cats and cause feline panleucopaenia.
Who is at risk?
All unvaccinated animals, but particularly young kittens.
How is it spread?
Infected cats pass virus in their urine and faeces for a maximum
of six weeks. The virus persists in the environment for long
periods (many months or even years) and is resistant to many
cleaning products and disinfectants. For these reasons, contact
with a contaminated environment is the most likely source of
infection. Kittens may also be infected inside the womb by the
virus passing across the placenta from their mother, if she is
infected while pregnant.
Signs and symptoms
Panleucopaenia causes severe vomiting, anorexia and fever. Sometimes
the disease can progress so quickly that a kitten may die before
the owner even notices any signs. The disease may initially be
mistaken for foreign bodies stuck in the gut or poisoning. Kittens
deteriorate very quickly because once they stop eating and drinking,
they become severely dehydrated. Older cats tend to show less severe
signs and, if queens are infected whilst they are pregnant, they
often show no signs of illness. The unborn kittens, however,
can be infected inside the womb and this may lead to their death ‘in-utero’ or
damage to their developing brains.
Cats that survive more than five days without developing complications
have a better chance of recovery although frequently it takes
several weeks for this to occur. If a cat recovers from panleucopaenia,
it is highly unlikely that they will catch the disease again.
Prevention and control
Treatment is typically supportive often including intravenous
fluids and antibiotics. Without intensive nursing, many cats
can die from the effects of the disease.
Most cat vaccines on the UK market includes panleucopaenia as
one of the diseases it protects against and is recommended for
all cats as part of their regular healthcare. Boosters are required
to maintain immunity and it is particularly important that queens
are up-to-date before any planned breeding. One of the vaccines
on the UK market has been shown to cross protect against the
canine parvo strains that can cause panleucopaenia.
