FPV, also known as feline panleukopenia, can make cats very sick and sometimes be fatal for kittens. Vomiting, diarrhoea, and even death result from it attacking the immune system and intestines.

Feline Herpes Virus (FHV) and Feline Calicivirus are the two viruses that cause cat flu. The symptoms of cat flu are similar to those of human flu, including fever, runny nose, appetite loss, tiredness, and sneezing. However, in cats, cat flu can also result in mouth and eye ulcers. Your cat may develop a lifetime infection and experience frequent flare-ups, unlike humans who often recover from the flu after a few weeks of feeling under the weather. For kittens whose immune systems aren’t strong enough to fight it off, it can be very serious.

The immune system is attacked by this virus, which leads to cancers including lymphoma and leukaemia. It also weakens your cat’s immune system, raising their chance of contracting other dangerous illnesses. You frequently don’t realise your cat has it until they are extremely unwell since the symptoms are generally nonspecific – weight loss, vomiting, lethargy, and diarrhoea. In order to maintain their health for as long as possible, your cat will require lifetime treatment for FeLV if they are diagnosed.
