Hand sprayers come in both manual and pressure spray versions. A manual version is the cheapest coming in around $3 to $7. It makes you squeeze the trigger for every spray while the pressure spray version allows you to put the water under pressure and then you just press a trigger to release your spray. The pressure spray version can be found from $10 to $50 depending on how big you want. You can get up to a backpack type unit if desired! The advantage to the spray bottle over the dripper is that you are increasing the humidity of the area while you are providing drinking drops. The chameleon can also use the spray to both clean out its eyes and defecate. The disadvantage of the hand sprayers is that you have to, every day, patiently keep spraying until through all stages of the hydration/hygiene cycle. You must have patience with this method and, if using the manual version, good wrist muscles to keep spraying until all stages of hydration have been completed. If you just spray down all the surfaces and let it go at that then you are hydrating, but not allowing eye cleaning. So either give your wrist muscles a big workout once a week doing a hygiene spray down or use a shower session.
"How to set up chameleon habitat" with water drip - YouTube
Chameleons have adapted to life in the trees and have become dependent on rain to drink and to clean themselves. Hydration (or drinking) is a slow gulp as the rain drips on them and flow into their mouth or lapping up water droplets after the rain or as morning condensation. Hygiene ends up being them sitting under a rain shower and washing out their eyes in the rain. When the keeper sees this happening for the first time they sometimes get concerned as they see the chameleon’s eyes undulating about somewhat unnaturally! But when this is done in a rain shower this is a good healthy thing! In fact, one of the common ailments that chameleons go to the vet for is eye infections that could have been prevented if the chameleons were allowed to engage in their normal rainfall. The hygiene part of providing water is one of the most often overlooked parts of chameleon husbandry so you can be sure it will crop up a couple of times before I sign off today.
DIY water dripper | Chameleon Forums
It’s important that you understand that chameleons need moving water in their enclosure to drink. In the wild they lick the dew from leaves. Chameleon won’t drink from a standing bowl of water unless they have no choice. So we need to provide a source of moving water for our chameleon through a drip system.
Excess water from my dripper! | Chameleon Forums
The Exo Terra Dripper Plant is a realistic plant that was designed to meet the watering needs of tree dwelling reptiles and amphibians like e.g. Chameleons. Arboreal reptiles generally do not recognize motionless sources of water; instead they drink from moving dewdrops and raindrops while foraging in the forest canopy. The Exo Terra Dripper Plant supplies a continual supply of cascading water droplets, attracting even the most reluctant reptile to drink. Regular access to a recognizable source of drinking water helps prevent illnesses related to dehydration, and will improve your animal’s overall health. This is how I drip water for my chameleons to drink. Keep in mind that chameleons are unlike a lot of other animals on that they do not typically drink standing water (ie from a bowl) but rather drink from droplets that collect on leaves. This is why setting up a dripper is very important in hydrating your chameleon.
