one of my 2 year old male rabbits died very suddenly yesterday, completely unexpected as he appeared totally fine the day before 
i am really worried about his brother though, i have taken both to the vets, one obviously to be cremated and to get the other checked over, he is running a temp so is now on antibiotics and the vet wonders if an infection is was finished off the other one.
my other concern is that bert is understandable lost without his brother, not eating much, although obviously this could be because he is unwell, looking for ernie in the run and hutch and generally looking very sorry for himself.
just wondered if any one else had experience of this, is it a good idea to try and find bert a new companion or would they fight, he is currently in an outdoor run as the weather is warm but we have an inside one for bad weather so was may be thinking of bringing him in until he settles? not really sure what to do,
thanks for any advice it would be greatly appreciated.
