Hello, There is an odd situation with my leopard gecko. She is about a year and a half old and I have had her since she was about a month old. Over the last 2 or 3 months she has gained quite a bit of weight and has bubbles under her armpits. I have tried various methods of getting her to lose weight and nothing has worked. Initially I tried to feed her half of what I normally did before. I was feeding her 12-14 insects every other day and I cut it down to 6 or 7 every other day. I also stopped putting her insects in a bowl and instead let here chase them in her enclosure (120 gallons) so that she would get exercise. When that didn't work I started feeding her 2 or 3 insects every day. She still didn't lose weight. I then decreased her feedings to about 14 or 15 insects twice a week, and then once a week. She still has not lost weight, and she still has bubbles under her armpits. The feeder insects I give her are black soldier fly larvae, crickets, dubia roaches, adult black soldier flies, and adult mealworm beetles. I took her to 3 different vets and none of them knew what is going on. I am wondering if her metabolism has slowed down due to brumation. My blue tongue skink is already in brumation. Also I should mention my geckos behavior has changed. She now spends all of her time in one of her 3 hides, and before she would spend alot of time basking under her deep heat projector. I am now preparing her for brumation. I have not fed her in about a week in a half and am planning to shut off her heat sources and reduce the time her lights are on to 6 hours a day at the beginning of December. Do you guys think her weight gain and change in behavior is due to brumation or something else? Should I go ahead and initiate brumation, or us there something else I need to do?
