Hello Everyone, This issue has been happening for a long time. My gecko (ever since I got her 4 years ago) has had spells of acting sluggish, and refusing to warm herself on the hot side of her tank. She will sleep all day and all night in her wet hide on the other side. She will eat, but then return to the cold side. This is concerning since they need to warm up to digest their food properly. So she has gotten quite fat as well (and I'm not overfeeding her). BEFORE YOU ADVISE, THIS IS EVERYTHING I'VE DONE TO TRY AND HELP HER: 1. I've taken her to the vet twice. Both times they gave me different advise. Once they told me I was giving too much calcium and multivitamins. I since have switched to only giving supplements once a week. The other they suggested I use a thermostat to keep the temperature in the proper range. 2. She lives in a 20 gallon reptile terrarium. It's nice and wide and has lots of things for her to climb on. She has a wet hide, and a warm hide. 3. I use a thermostat to make sure the hot side is at the right temperature. Typically the temp is anywhere from 86 to 90 degrees on the hot side. 4. Typically I feed her dubai roaches, giving her multivitamins once a week. 5. Sometimes I reach in and place her on the hot side myself so she will get warm. She will bask for a bit but then return to the cold side. I know that the hot side is not too hot because I use a temperature gun to make sure the surface is in the right range along with a thermostat. 6. I use heating pads. I have briefly tried small basking lights (though not recommended) to see if perhaps she would prefer that. She shunned those even more than the heating pads so I went back to using belly heat. I am literally pulling my hair out over this at this point. If I had realized it was so hard to keep a leopard gecko happy I would have never gotten one. I feel like a bad pet mom but I've spent so much money and time trying to make her happy. Please any suggestions are appreciated. She seems to spend most of her time sleeping on the cold side, inactive, and when she is on the warm side her eyes are squinty as if she's hardly awake. Thank you.
