The panthers are far more colorful than veileds. My panther is a decent amount bigger and WAY friendlier! I know some others have very friendly veileds, but mine hates the world and anything in it. But my panther likes to explore and paces at his cage door when I come in the room to be let out. Not all panthers are that friendly of course, I know some are aggressive also. Personally I like the color and personality of panthers but it's really a personal preference.
