You said..." she began getting very tired and wouldn't want to move at all. She closes her eyes for more than 90% of the day and the 10% she has them open. While her eyes are closed, she still moves, flailing her hands out looking for anything to hold onto. Her grip still feels strong and healthy, so I don't think she is lacking nutrition"... There are a number of things that could be contributing to this behavior in a chameleon.... if a chameleon. Is cold it might want to sleep during the day. If it's sick it might behave this way. If it's got a blockage or lacks proper nutrition and hydration it might behave this way...etc. this is why I'm asking the questions....so I can try to figure out what's going on.
You said..."she isn't eating anything,its been maybe 4 days since she ate, she has plenty of crickets in her cage,
but she won't eat. While they crawl on her, she flinches, so I know she can feel them. I took her out to try and hand feed her, but she would ignore the food"...were her eyes open or shut?? I would not be leaving insects in her cage when she is defenseless like this or you may find out they will chew on her.
You said..., "She hasn't been very protective of her territory recently, just letting me pick her up as I please, which is really odd, since she hates when I'm in there"...this is because she has something wrong with her too...hasn't got the strength or desire to try to protect herself.
You said..."She hasn't went poo in a few days, and I'm thinking she may even be constipated, if that is common is chameleons"...if nothing's going in her mouth then nothing's going to come out the other end. As for being constipated ...if she's too cold she can't digest the food properly so she can become constipated. If she's overfed constantly she can become constipated. If she is not hydrated properly she can become constipated. Etc.
You said... "she would occasionally make a quick vibration , almost like a phone going off, it wasn't audible until I got like an inch from her"...that's part of the way they communicate.
Back to the questions again...
- Feeding - your gutloading/feeding needs improvement. Those orange cubes aren't much good IMHO. It's important to look after your feeders well. I use dandelion greens, kale, endive, escarole, squash, carrots, zucchini, sweet potato, sweet red pepper, etc and a SMALL amount of berries, melon, apple, pears, etc.
- Supplements - how often and how heavily do you dust the crickets? It's recommended that you dust the insects just before you feed them to her at almost every feeding. It's also recommended that you dust the insects with a phosphorus-free calcium/D3 powder twice a month lightly and with a vitamin powder twice a month.
- Watering - your misting isn't long enough...chameleons are slow to start to drink and need a longer time than that to get them started. You should be running a dripper for quite a while every day too. It can be a deli cup with a tiny hole in it so it drips at the rate of one drip per second. I think you said she's not drinking much from a syringe.
Cage Info:
- Lighting - a UVB light is needed somshe can produce D3 or she will end up with MBD.direct sunlight that does not pass through glass or plastic is fine too for that. All lights should be off at night. Lights should be on for 12 hours and off for 12 hours.
- Temperature - as I said ...without knowing the basking temperature or the temperature in the rest of the cage I can't tell if she has enough heat to digest her food or if she's constipated because she is too cold. You need a thermometer.
- Plants - it looks like you should have more greenery in her cage.
