The panther is nice, but compared to the Poser lion, it hasn't seen a lot of third-party support (textures, morphs, characters, etc.).

Even the worst animal figures will benefit from a high-quality texture (example: the Poser cat with Daio's Purrfection textures).

A wolf figure is already included in Posers 4-5. Lyne Masamitsu has an excellent expansion pack of morphs and textures at Vista Internet Products, bloodsong has a free remapped version of the wolf at 3D Menagerie, wolfie has a remapped wolf (with additional morphs) here in Free Stuff, and I have a Mimic-ready version and some replacement eyes that I'd be glad to share.
