As i told you before im keeping Leonardo's cage next to a huge and almost always opened window in my daughters bedroom. So he lives according to the outdoors weather. Now its the rainy season in Malaysia and the weather is cloudy and more cold (78F -90F).Since the start of the rainy season Leonardo became diurnal!He is active during the day from 8am to 9pm and i havent seen him hidden in his hiding box!He eats, poops, explores his cage and begs to go out during the day like a "normal" pet!Is it possible the MTSs are nocturnal during the summer and diurnal during the rainy season??
