I don't know if there are any other rabbit people here. I started with 6, was too careful with my control of the breeding, and ended-up buying some rescue rabbits from owners, who weren't keeping their rabbits under good conditions. At one point (about 2 years ago), I had 17. Many of them died from, what now looks like, heart conditions. The mother, Silke, just died last weekend from complications due to heart conditions. After losing my precious Hugo (about 8 years old - a rescue rabbit) in January, too, I'm down to 9. I'm trying to breed them, but I have 3 females. One has a definite heart condition and the other two are the children of Silke and Hugo. The eldest is supposedly 5, but Hugo's owner lied about his age. We only found out, when he started showing signs of old age (means about 7) when he was supposed to be about 4 years old. The others are 4, 3, 3, 3, 3, 2, 2, and 2. One of the 2 year olds is Silke's Grandson, and is already showing signs of a heart condition.
