Hiya, oh dear poor little man..and you too, well agreeing with the others...no i wouldnt force feed him either ,wait to see the vet but try to get in sooner...say its an emergency and perhaps they may see you sooner!!, i would start though by taking the night light away all together, chameleons need a good night time temp drop and can cope with quite cool temps at night and compleat darkness at night is very important to help them sleep properly so check the temperatures recomended for your specise and try to match these and if he does need a little heat at night...if your in a cold area perhaps use a ceramic bulb instead as they emmit no light, just heat but it will need to be on a thermostat to control the heat output as they can get very very hot ..i dont use any heat at night on my chams and i live in the u.k so does get cold here! and they are just fine, also as he a baby he may not be able to take the higher day time temps that an adult panther would so perhaps a little cooler by a few degrees as heat can kill reps quickly, make sure the u.v lamp you have is working well its a good brand you have but check it isnt old or it could be deficiant in the u.v output which can effect him and his metabolism, and make sure he isnt dehydrated ( very important!!)as babys do get this very,very,very easily!!!, so keep spraying his enclosure and him too...but gently tho with warm water(not hot!!)for ten 15 minutes at a time at least twice a day to keep up the humidity and also to stimulate him to drink as they wont really use bowls to drink from, i have had to in the past give a sick chameleon water via a clean seringe barrel ..a few drops at a time into his mouth , waiting while he swalowed each drop so as not to drown him, i hope these ideas can help you in some way but definatly a very prompt visit to a herp vet !!!!, or it may be a sad ending!. but i will keep my fingers crossed for you. good luck and keep us informed ok.
