Surprisingly it can be passed from cat to cat quite easily. Transmission can occur in a number of ways like grooming each other, cat fights (scratches and bites), sharing a litter box, or simply through sharing food and water bowls.
Something you might not know about Feline leukaemia is that it is not a strong virus. It can only survive around 2 hrs in a dry environment and about 48 hrs in a damp environment.
The virus is an immunosuppressant in cats. This means that the immune system becomes weak and finds it hard to fight off other infections, in turn becoming sick a lot more often and worse than say a normal healthy cat without the virus. Some signs that your puss may be affected by the virus are vomiting, diarrhea, breathing problems, eye problems, lameness and fertility problems. Unfortunately there is no cure for feline leukaemia, only prevention through vaccination, so make sure that all of your vaccinations are up to date and you shouldn't have a problem!By Lauren, Vet Nurse.
