make sure you are gutloading your crickets really well with juicy fruits and veggies,this will help with your chams hydration levels alot,it may take a little while for re hydration to occur..just keep misting and keep watchin your cham..if its drinking now this is good..mist till your cham licks its lips and then it should drink more..a light misting on your cham may help too..give it a little more time...my chams urates are almost always white,but every once in awhile they have a tinge of orange to them..guess it all depends on the amount they are drinking at the time..
It can also mean that the animal has not pooped recently, the longer the urate stays in the body, the more moisture is reabsorbed by the body. It does take a couple of days to see the results of better hydration. Keep pressing the liquids. If you've seen Tanzy drink for 4 days in a row but there's been no change in the urates, I'd vote for a visit to the vets.
