we had two buns which came together as a pair.
They are always grooming each other and always within a metre or so of one another, even though our garden is a good size..
Yesterday one bun just died (6years) in his cage overnight. Other seems sad and is hardly moving- just laying in one of two spots.
Should I get a companion quickly or let him mourn? We are devastated by the loss of the one and do not want to lose his brother too.
Any bunny experts know the best way forward?
