You said..."my female veiled chameleon who laid eggs about a month ago has been acting extremely strange recently"...how many eggs did she lay? Was she with a male? Did she dig a hole, lay the eggs in it, fill it in and return to the branches?
You said..."I dont have the money to take her to the vet so i came here, She used to ask to be picked up everyday but she stopped that, also recently shes turned really skinny"...photos please! Is she sitting low in the cage, sleeping during the day, lethargic?
You said..."yesterday i caught her acting like she wanted to throw up but she didnt throw up. Also sometimes when i mist i realized she runs to lick the water off the walls so i spray water in her mouth and she drinks it"...is she just opening her mouth or sticking her tongue out when she's doing this? Is her nose pointed down or up in the air? Does she do it only when you're spraying water in her mouth? BTW...you should not spray water into her mouth, you will likely get it into her lungs and that is bad news....and could be why she's acting like she wants to throw up.
You said..." ive also realized that theres white poop that dried and looked like it was blocking her way to poop so i cleaned that twice in 2 weeks. I was wondering is she dehydrated? Is she not getting enough vital nutrients??"...if the urates are white then she shouldn't be dehydrated. What do you feed her? What do you feed the insects? What do you dust the insects with? Please be specific...please look to see if the powders you dust with have phos, calcium, D3 or vitamin A in them and what form of vitamin A (look for words like retinol, beta carotene, acetate).
You said..."Ill post pictures of her when i get home"...thanks!
She could be having a reproductive problem or a nutritional problem or it might have to do with the watering...or even something else. The information were looking for should help us figure it out.
