It sounds as if the risks are low. Carrie said that there had been 87 cases in the UK over the past 10 years. I imagine that the feline population in the UK is in excess of 10million cats so the risks would literally be "1 in a million" chance, if that. I would suspect that the risks of other fatal illnesses oor conditions would be far greater? Certainly where it is common to let your cat outdoors, the risks of FELV/FIV would be MUCH higher (even if innoculated).
