ken and kim - I am so sorry to hear your sad news, especislly as it seems so much like what happened to me the other year. I think the symptoms of the reddish bottom is a bladder infection, and that is what your rabbit most likely died of, and reddish colour is blood in their urine. I am so sorry for your loss, but if it comforts you at all in the previous days, weeks and months before the day my rabbit died, she was extremely happy and content, and must not have felt ill or in pain until that last day and even then she didnt seem distressed just sleepy and distant, it was only going to the vet and having the vet examine her that was painful and your rabbit stayed home where it felt safe your rabbit didnt go through that. So you can feel comforted that your rabbit didnt suffer she was happy and running around until she just fell off to sleep,to wake in rabbit heaven with my beauty, running free in the wide expanse where carrots grow wild.
Best wishes.
