just out of curiosity isn't 6 months a little young to be gravid?? i know its said that veiled can breed at 6 but i everything i have read or seen said that panthers do not mature enough to be gravid until 9 to 10 months...
Definately a girl, but I would put out a laying bin just in case. Her colors do look like she could be gravid and if the pet store is wrong (how often is a pet store wrong!) she could be and you should be prepared. Make sure she has her calcium supplementation.
She is very nice looking, Those colors are from stress or she is gravid.She looks like she could be carring eggs.I too would get her a laying bin and increase her supliments
