Maintains Ideal Environment For Tortoise And Reptiles --- Cold-blooded species such as snakes, turtles and tortoises cannot change their body temperature independently with their environmental temperature. By using a Stick-on Thermometer by SunGrow, you will be able to monitor and maintain correct temperatures that directly affect the overall health of a domestic turtle or tortoise. Regulates Body Temperature Of Cold-Blooded Species --- Since body temperature determines the rise and fall of activity levels of these cold-blooded animals, they need to be able to regulate theirs along with their environment. Failure to do this may lead to health problems. Keeps Your Cold-Blooded Pet Healthy --- On-stick Thermometer helps in determining if your reptiles and amphibians live in ideal temperature conditions. Living in an unsuitable environmental temperature can cause a lack of appetite and may be the cause behind ill-health of your prized pets.
