Luna, beautiful tri blue merle border collie

This is an extremely difficult decision which has taken some thinking and family discussions to make. Luna is an absolute star, she is so cuddly and super loving. She has good recall, she has been raised with children, other dogs and pets (please read all of the description). She is so beautiful and has a sweet disposition. She is fully inoculated, up to date with flea, worming, is micro-chipped and she is neutered. We've had her in our family since she was 8 weeks old. She loves nothing more than a cuddle and a bed/sofa to sleep on. She is fully house trained, knows basic commands and has the sweetest beg command. She is crate trained, travels well and can be left alone for periods of time. Now for the reason we are seeking a new home for her, she has a very high prey drive and although we've had cats all our lives and Luna has been raised with cats since we've had her, she will not leave them alone at all. This has gotten progressively worse to the point she will not eat on her own as the obsession has taken over her. We must stress she absolutely must not be re-housed with cats and or smaller animals. This is important and an absolute must. Luna is loved dearly and please don't be put off if we ask questions about your household and lifestyle. This is to ensure Luna will go to someone suited for her and her suited to you. Thank you. *Luna has never hurt a cat ever, we're just concerned over her obsession with them as she's not resting or eating properly and it isn't fair as we see it as being on edge all the time*
