Around 9 months ago i bought two dwarf lop eared rabbits, i was assured that they were sisters, however 8 week ago i woke to a little of 8. Two weeks ago one died suddenly with symptoms of illness only showing an hour or so before, and again today another died in the same way. They both seemed to have lost weight over night, they became unstead on their feet until they were unable to walk and then began to have seizures which they died soon after. The other babies seem to be healthy however i have noticed today one has conjuncitivitis and im wondering if this could be passed on by the ill rabbits that have past away? eventhough they had no signs of this themselves. I am unsure if this is common as i am unable to vist the vets until the morning? is there anyway in which i can prevent this from happening again?
