I haven't posted here in a while but if you remember me at all, you will remember I lost two bunnies and one nearly passed. I got Mindy my older rabbit whose 2 years old now and she had babies unexpectedly. The other male rabbit she had been with was her age, looked the same, all the same age I had a worrying feeling they had been bred brother and sister, the last owner denied this but I know for a fact they were brother and sister. I googled and I found people saying its okay to breed them, others saying not, well I am telling you do NOT breed brother and sister, for the love of God do not do it! Its unfair on the rabbits and anyone who purchases the rabbits from you. I have the last surviving rabbit now. I found out today the two I gave away died very recently of the same difficulties all the other rabbits have had and my miracle Phoebe whose now 1.6 years nearly died twice.. she became ill this year with blindness in her eye which was a brain tumor and had to have the eye removed, she would have died had i left it a week longer, well her sister it turns out passed away 2 weeks ago blindness in the eye and then fitting and seizures. I am counting my lucky stars but my heart breaks for that poor girl I gave those rabbits too and they died at a year old and one a year and a half old. All the same conditions. This is without a doubt due to brother and sister being bred so please whatever you do if you're thinking about it do not make this mistake!! My Phoebe is a fighter and a miracle, I count my lucky stars every day shes with us, she nearly died at 4 weeks old and again as i said earlier this year, the tears I sobbed and cried.. it was horrible and now after hearing she's the only survivor I have fears she may not live the long life expectancy I'd like her to.. but I have to hold onto hope. Don't put yourself, the rabbits or the people you give those rabbits to through that.. and don't think because difficulties don't arise till a year after you give them away it isn't your fault or due to your breeding... because trust me.. my two bunnies who died at 8 weeks and 4 months, they died of same issue as this poor owner has had to go through with a year old rabbit, i warned her after that one passed, and sadly her last one has also passed now... just don't do it, please, think about those involved. That's all I have to say.
