Hi Crazy,
There are several ways to tell if your chameleon is not getting enough water and is dehydrated. The first and foremost way is by lookin at their eyes. If they seem shrunken, shriveled, or if even the pupil itself seems cloudy, they need more water.
Second way, is look at their skin. Are there creases in his body? If you were to grab softly and pinch together the skin a bit, does it replace itself in a natural position? Or does the crease remain? If it remains a crease, he/she is dehydrated.
Third way, is to look at their urates. The urates are a part of their fecal that usually drops to the floor. There will be some dark parts to his droppings and then also either a white piece at the end or sometime it may look a orange color. The white and orange colors are his urates (urine). If they are white... good sign! Your chameleon is getting the right about of water. If they are orange in color, that means dehydration.
Make sure you have a good dripping system or at least mist your plants heavily 3 times a day. Frequently, showers will do wonders. I will cut and paste about showers that I have posted in other threads about this subject. Your chameleon will love it and he/she will get a nice long drink that will immediately help dehydration.
Copy: Chameleons should not be sprayed directly when misting in their cage. Always mist the plants. If your chameleon is dyhydrated do the following that I suggested in another post on this forum about this subject:
Try a shower. I have a little tree in my shower (a silk tree so as to not cause overwatering a live plant) which I use to give all my chameleons soft, warm showers... Make sure the water is not hot or not too cold and not on full blast (this can hurt their eyes). Run the water softly as if soft raindrops were floating down, put your little tree under the "pretend" soft warm tropical rain and let your chameleon have a very enjoyable shower. If very dyhydrated, he may stay in the shower for 30 mins or more drinking. You may see him stretch his head and neck up as he drinks... this is normal. Let him drink as long as he wants... when he starts to get restless or stops drinking, then remove him from his shower. Make sure you place him under his basking light afterwards so as to not get chilled.
He will love it! All my chameleons turn happy colors when they see they are going to get a nice warm tropical rain in my shower .
By the way, a shower is NOT recommended for baby chameleons. Wait until they are big enough (4-5 months old or more) so as to not drown.
My chameleons love showers Crazy.. and it helps to keep them good and hydrated as well. Try this once or twice a week in addition to you providing a good amount of water/misting as well.
I hope this helps!
