Infected cats should be kept isolated from other cats
The virus spreads from feline to felilmne contact and with contact from the discharge from the eyes and nose. It can also spread from the cat sneezing quite like a cold is spread in humans.
The virus can exist outside the cat's body for a period of time so therefore infection can be transmitted by way of bowls, cages, bedding or anything your feline comes into contact with. You can also spread the virus yourself from one cat to another via your hands or even on clothing.
The Herpes Virus can survive outside the cat's body for about 24 hours but the Calicivirus can survive as much as 7 - 10 days
Household bleach mixed at a ratio of 1:32 is an economical and effective way of destroying the virus on washable items.
It is a fact, cat flu cannot be spread to humans.
Feline Herpes Virus symptoms generally last for about 7 -14 days and Calicivirus symptoms usually last for about 7 - 10 days.
When felines have recovered from Cat Flu they still shed the virus particularly at times of stress. Even though they do not show any signs they have indeed become a carrier of the virus.
With Feline Herpes Virus the carrier state can last the entire lifetime of the cat.
With Feline Calicivirus the carrier state continues for at least one month after infection. Over half of infected cats eradicate the virus after 2-3 months and most cats do purge it completely after 18 months.
There are vaccinations obtainable for Feline Herpes Virus-1 and Feline Calicivirus (FCV) Talk over a vaccination regime with your veterinarian.
