Rich – I agree, sometimes these things happen. i remember when I was baffled as to why one of my bunnies died. The necropsy offered up more questions than answers, and I remember my vet saying….this is part of having a rabbit. Meaning rabbits can be very mysterious when it comes to health. They have very sensitive digestive tracts that can react to anything – something new to diet, stress, other health issues and so sometimes the only clue that there is anything wrong is is by watching whether they are eating, drinking and pooping, and if that stops, then that can cue us into some problems, but sometimes…everything seems normal and they still leave us without warning.
I am sorry as it is very painful and we all here can definitely understand how hard it is. Once you have had some time to heal, maybe you can share with us what Mina was like so we can celebrate her life and let that be the focus.
