We have one young rabbit inside the house that has fleas. How do we treat her for fleas? Also, we have one older rabbit in a hutch outside and I have noticed in the evening that mosquitoes are buzzing all around it. Will they make her sick? There is a outbreak of West Nile virus in this state. We have walked around our property and made sure any container is turned over or covered so that it will not hold standing water but we have neighbors very close and do not know what is on their property.
