If you are interested in an offer involving jc panthers plus various pets you can message me at Vasala#1465 (I currently have the mats to make all 4 of the individual panthers or turn that into a jeweled onyx.)
The spectral kitten seems to range from 145k to 200k. There was a point when they were going for less due to fear of a pet with the same skin being sold at the blizzard pet store. But, that confusion was cleared up on twitter with multiple posts.
That being said... I would be interested in trading for yours as well.
