Male doesn't want to eat, losing tail fat, but no change in weight

My male gecko doesn't want to eat. He used to love his baby meal worms to death, and now he won't even look at them. He gives up chasing crickets after he misses the first two lunges and he doesn't even recognize waxies anymore. His tail has definately gotten thinner, but not to the point where it's worisome. The wierd thing is his weight hasn't changed a single gram, been the same 47 grams for the last 2 months.

Crappy thing is, since he's not eating, he's not pooping often enough for me to get a decent sample, and since it's so sporadic I never know when he'll drop me one (and by the time I see that he pooped, the sample is dried out and no longer useful).

Do I just wait him out, or should I invasively get a sample from him? He doesn't look sick, but him not eating is worrying me.

Invasively getting a smaple from him...that scare me a bit, a lot can go wrong and you can hurt your gecko badly.

About his eating habit, i would suggest some baby food on his lips so he can lick it up. Maybe somebody have a better idea ?

If you take him to a good reptile vet, they can do what is called a "cloacal wash", and get a fecal sample that way. Better to be safe than sorry, I would have him tested just to be sure.

Good luck!

Is your male in with any females, or in a room where breeding might be occurring? Of so, you may want to consider moving him to a location out of range for the breeding "pheromones" to affect him. It is not uncommon for males to lose interest in food when there are ovualting females around.

I do not recommend doing any type of invasive sampling yourself, and agree with Kelly that only a qualified vet should do it. I am not sure if that kind of stress is what he needs right now if you aren't that concerned with his weight loss at this time. I like the baby food idea... get some baby squash (it is an intestinal binder) and dropper feed him by putting a little on his nose and squeezing out 1/2 - 1 ml. as he laps it. This should give him something for a good carbohydrate as well as provide enough stool for a fecal exam.

Now there's the crux of the problem, "a good reptile vet" doesn't really exist around where I live, and the only vets around do more harm than good. Which is funny because Central Michigan Uni is known for their awesome vet program and they're just a few hours away, pity I don't have a car to drive up there.

No, no females anywhere in sight.

Yes, cloacal wash was what I was referring to when I said "invasive". But, I'll try the squash and see how it goes.
