Last night I fed a group of young radixes. They are 6 months old. All good eaters. Everyone filled their bellies and went to bed. This afternoon I looked into that enclosure and saw one of the little scrubs out. She was obviously disorientated and having trouble moving. Her pupils were constricted and there was no tongue flicking. I picked her up and she seemed to recover for a few seconds but then lapsed into the same condition as before. I held her in the palm of my hand until she died. Before dieing she curled into a circle and bit herself on the side. She died with her mouth open.
I never saw any of this coming. It's probably due to some developmental issue/s but losing them doesn't get any easier.
