I got my monitor just a few months ago from the same pet store I got my sugar gliders from. I knew he was healthy, well cared for and that the store owners honestly care about the animals. This was my first time owning a carnivorous lizard but I had owned an iguana and Chinese water dragons as a kid, as well having successfully hand raised orphaned pet rat babies. I also worked with snakes through most of my middle and high school years so I was familiar with the various needs of a reptile. I had done my research prior to choosing a Nile monitor (I actually debated between Nile, Savannah, and Water monitors.) I thought I knew what I was getting into but I know from experience that pet ownership is a constant learning experience. With all that said, I'm really concerned for my Burundi. I've been giving him gut loaded crickets dotted with a reptile vitamin. He never ate more then five at a time and only ate every other day. I've been breeding the crickets myself so I could monitor their health and eating. I recently moved Burundi to a larger enclosure (from a 20g tank to a 50g) and now he's stopped eating. I checked the temperature and it's still in the high seventy, low eighty range through out his enclosure except his basking spot where it reaches a good 110. I also switched to a bigger water dish and included a small, hand built misting system to add some additional hydration. I clean this dish out daily. Because I was concerned about if he just wasn't getting enough full spectrum lighting, I went and purchased a new UVA/UVB light for the primary lighting. It's now been ten days since he last ate. I took him to a highly recommended exotics vet and was told nothing was wrong. But my monitor is losing weight and I'm getting nervous. I started just giving him straight vitamins yesterday, two drops yesterday and two today, just so he's eating something. I found out my former father in law is breeding dubia roaches and he's going to bring me a few tomorrow. I'm hoping since they don't jump around like crickets do, it'll be easier for Burundi to catch them. Should that fail, I want to know what I should do next. I've scheduled another appointment with a second vet about two hours away but my time restraints forced me to make it a week out. And because I'm sure it matters, he's housed on ReptiBark, drinks filtrated water (if I won't drink it, my pets don't drink it), and I'm using Fluker's Reptile Vitamins. I order my gut load for the crickets from the same person I get my sugar glider's food. She eats the same crickets and has shown no signs of illness. The crickets also get calcium enriched Fluker's Cricket Drink. When I purchased the tank decor, I steam cleaned all plastic items and put the wood in my oven for a short period to kill anything that might have gotten on them at the pet store. I really don't want to lose Burundi. I don't have pets. I have four legged children.
