hi guys thanks for the replies i'm in Dallas,TX my BP was a rescue it came with a 40 gallon breeder the snake was eating fine,but i knew i coudn't keep good temps on a glass enclosure so i bought a pvc one slighly bigger 36x24x16 the old one was a 36x18x17 so not much of a diference since then my snake has gone off feed but the snake is fine in there the tempes are perfect he spends hlaf of the time on each side and every night the roams around since july he ate twice a FT and live offered live,frozen,rats,mouse,white and black but nothing works i have to force feed and liquid is the easiest way my snake is skinny i'm going to bring the weight back to 400g then ill try feeding again normally.The only risk with syringe feeding is getting down the food in the traquea but is hard to do as the hole is on the bottom of the mouth my BP is over a year old and weighing 300g i can't let this go on anymore,also i know the temps are good my snake is been on that enclosure for 5 months i'm not changing.
My bearded dragon was also sick and he also would not eat so i also force feed and shes back on her feet now eating on her own but beardies are alot easier to feed as when you put something in the mouth they will chew it and eat it.
I'M going to tell you my experience with vets,they don't know the animal you as the keeper that is your job and the information you find online as it is very good info.i leave the medical side to the vets like fecal and so on.i took my BP for an examination a 2 months back the fecal came back negative.i'm going to try this approach and see if my BP will eat on her own in 6 weeks from now.
