So I am freaking out right now. I have had three rabbits get random respiratory illnesses in the last two months. First died within 24 of getting sick. The second a nursing mom I am treating with antibiotics whom only symptom is a making sounds while breathing. Now I found a third with snot today. I am just not sure what to do. All were vaccinated with bunny vac. Should I cull the effected? I am going to get the snot tested to see which bacteria I am dealing with. I have never had a respiratory outbreak like this ever. Advice please?
