To me, as long as you're drinking a bottle of water with it I see no harm. You get hydrated from coffee. Of course you need to drink water in general, but the concept of drinking cups of water to balance out dehydration from coffee is just a myth.
Reptiles do not maintain their own body temperature within a narrow range like mammals and birds, so controlling their environmental temperature is critical for normal activity and good health. Reptiles are poikilothermic-which means that their body temperature alters with the surrounding environmental temperature.
If air temperatures do not suit them, some reptiles can hibernate until the temperatures are right again. Another unique characteristic of reptiles is their eyes. The shape of a reptile's pupil, the black spot in the center of the eye, indicates whether the animal is active at night or during the day.Most reptiles active at night have slit-like pupils that can close tightly in bright light.f air temperatures do not suit them, some reptiles can hibernate until the temperatures are right again.
