Here's a cute cartoon of a spotted leopard. This graphic is available as a scalable vector graphic as well.
Cartoon of a leopard changing his spots.
This one is the face of a cougar, although I once knew a house cat with a face very similar.
The face of a panther staring a person down. Beautiful, but I'm glad it isn't me it wants for lunch!
And two more graphics of leopards, this one lounging on a tree branch...
and another that might be on the prowl.
This picture of a jaguar is available as an SVG if you need a large version or for print.
