Bonded pair Onyx and Opal

I have had Onyx (male) and Opal (female) since they were 12 weeks old, and prior to that they were with their mother. They are now over a year old and they have been a bonded pair even prior to coming into my home, which is why I adopted them together. I have been so glad I did, because they are best of friends and keep eachother company when I am away at work.
My work schedule is about to change and I will need to be going out of town. There will be no one to look after these two cuddle monsters so I am seeking a new home for them. They are absolutely wonderful pets and I know they will make someone else's home very full, happy, and fun.
Opal can be shy with new people and can take a while to warm up, but once she is comfortable she cannot be pet or cuddled enough! They are both extremely cuddly. Onyx is not shy and loves attention. They are both mild-tempered, loving, and playful.
Onyx is a large cat around 12-15 lbs and black with a grey belly, longer haired. Opal is smaller around 10 lbs, black and medium haired.
They are both spayed and neutered and up to date on all their shots.
