We hadn't had them for long - we rehomed them earlier in the year from a lovely lady who just didn't have the time for them anymore but they were so well looked after and really loved. They were sisters and approximately 6.5 years old.
Well this morning, everything was fine, I went out in the garden and they were fine, went back out an hour or so later and Rita had sadly gone to sleep and died it seems 
We have buried her in the garden but her poor sister Janet looks so sad.
We are wondering what the best thing to do now is - do we keep her as a solo rabbit? Bear in mind she is kept outside, she has a very large hutch which is left open and she has free run of our (very secure) garden. Unfortunately she cannot be a house rabbit as we have several cats and don't have a spare room to dedicate to her.
Do we get her a new rabbit to try and bond with? And if so, are we best getting a younger rabbit or an adult rabbit? Male or female? I have read online that the best thing to do is get them a new mate but I wanted to hear other people's personal experiences - this is the first time I've ever owned rabbits.
I have attached a couple of pictures of her, she had a fantastic mullet
