Panther or Veiled???
I don’t know how many times I’ve heard this question, so I’m starting with it. As far as chameleons go, these 2 are about as close as they come, as far as size, cage setup, temperatures, etc. They are 2 of the larger chameleons, both hardy by chameleon standards, and both are very available as a pet. A veiled chameleon will get slightly larger than a panther chameleon. A veiled also tends to be more aggressive. They will both need large cages as adults and lots of perching sites and trees or large plants, as outlined in the caresheet. Veiled chameleons are better at withstanding hot temperatures and lower humidity. Veileds will eat plants, like the leaves of ficus benjamana and most vegetables and some fruits, such as small broccoli tops, raspberries, blueberries, romaine lettuce and even hibiscus flowers more readily than panthers. Veileds are also much more aggressive at eating vertebrates.
