hello i have an adult male leopard gecko. he’s 4 years old and lately he’s been refusing to eat.this has been going on for little over a month. this started at the beginning of february. anytime i would offer him food he would ignore it and walk away. he hasn’t lost much weight as i can tell but this is still pretty concerning for me. his tank stays about 80-85 degrees fahrenheit on the warm side and his basking area is 90-95 degrees the cool side is about 70-75 degrees.
