Can my dog or cat get West Nile Virus by eating an infected animal?

Experimentally, it was found that this might be possible. However, there has been no evidence to indicate that West Nile Virus can be naturally transmitted to cats or dogs that carry or consume infected animals. Dogs and cats can be infected with West Nile Virus through the bite of a mosquito, so minimizing their exposure to mosquitoes is recommended.
