yes i agree, a female can lay eggs with out a male, and the tmp is too high, i think she might be dark in her cage and won't let you hold her because she is adapting, may cham ( female veiled chameleon ) did that as well, don't worry she will be fine. she should "finish adapting" pretty soon...
i think you should find some place on the internet you and other people trust, or you can get some information on places that are trusted by your vet, if your lucky the vet could, my vet can
well its all a matter if the female is ready,try to put them together and if your female is showing signs ( turns bright and black) then she is not ready, but sometimes there is no signs, they will just fight so try putting them together some other time ( in about 3-5 months id say) but maybe...
yes, they can eat other small lizards, but i dont see any use of doing so, it is bad for thier digestive system so i would just stick with worms and crickets :)
