Though I commend you for saving her from Pet Smart.......don't be overzealous in your endeavor. Especially now that she IS in good hands.
She looked pretty healthy at Pet Smart, and now she looks a little plump considering it's only been 7 days.
There is always the argument between overfeeding & underfeeding; but really the best thing is the middle ground. Calorie restriction has long been proven to be beneficial to health and lifespan....when people overfeed themselves or their pets, that's when problems arise.
For chams, and this female veiled in particular, if you are feeding her too much she will produce too many eggs and eventually this will lead to a short lifespan which is very common in the hobby. Female veileds should be living 8 years but they commonly only live 50% of that.
Females of any species are designed to sacrifice everything for the survival of their offspring, if you are aware of this you can't manipulate it and slow it down. My female veiled died at just over 8 years old in a hole she was digging to lay her last clutch.
