I'm thinking his branches may just be too small as I do see him using his rear legs however it seems he has some sort of muscular weakness in his rear legs.
UVB and UVA bulbs replaced last month, he gets d3 and calcium daily, I dump calcium and d3 into his mealworms bark and shake it up so when I pull them out they are already coated in his supplements.
I've also now added a liquid syringe multivitamin/supplement to his diet, which I give him 2 drops while giving him water. The supplement is new and I just started yesterday, and would be unrelated to any weakness. Today he seems to be a bit more energetic and his rear legs feel as though they have more strength to them, he's crawling around on my shirt as I type this.
I want your input as you may have more experience in the husbandry of chameleons and may have been able to identify this early on in your own chameleons.
I'm hoping more careful husbandry for this little guy will stave off any symptoms of it. Will continue d3 and calcium with regular watering and A&B bulbs, the bulbs are high wattage and he's in a mesh enclosure, enough ambient heat gets down to his vines for him to comfortably bask, I just wonder if his twigs are getting too small for him or if this is a sign of something more. Thank you!
