After my original post I decided to dig this movie out of my collection and watch it again.
I had forgotten that it has a very sad ending.
The main story line is about GG (the pet) and her owner. It starts with her life before becoming a pet and is done nicely. There is also a sub-plot about slave traders which I think should not be in the movie, but was probably added to give credibility to the vanilla viewers. This sub-plot is what gives the movie a sad ending.
I still recommend it since the pet/owner relationship is done nicely, but I thought I'd warn you about the ending since kittens tend to be more emotional then other pets.
That movie made me scared :( It such a great beginning, but such a horrific dark painted ending, is really very anti bdsm in general...It could of been so much better, such a shame really. They were also putting a design on making the cage into a real cage, which I was against as the diameters of it were unsuitable for keeping a human in. (Eg possibility of blood clots from cramped positions etc.)
