I can not get her cage to be over 80 degrees. The best way to heat your Red Tail Boa's enclosure is with a combination of a heat mat and ceramic heat emitter. Adult (6’ to 8’) — 6’L x 3’W x 3’H. Juvenile (2’ to 5’) — 4’L x 2’W x 2’H. Large adult (longer than 8’) — 8’L x 4’W x 4’H. She is doing really well and just ate her first 2 pinkie rats.
Occasional humidity measurements higher than 70% are unlikely to do harm unless the enclosure is not allowed to dry. Fortunately, it's fairly simple to maintain proper humidity levels inside a boa constrictor enclosure. For example, when your boa is preparing to shed its skin, consistent humidity between 75-85% can help the snake shed in one piece (healthy). I just got my red tail boa a couple days ago.
The optimal boa constrictor humidity range fluctuates between 55-75%. A good rule of thumb for boa enclosure dimensions is: Baby Red Tail Boas can also be kept on paper towels or similar product until they become juveniles.
In my experience, boas do best when kept under the following conditions. The increase in humidity will allow your red tail boa to shed faster and easier. The overall humidity in the cage should be about 60%, with additional moisture provided whenever the snake enters a shed cycle. After the shed is complete, you should lower the percentages back down to 50 – 60%. Heating As with all reptiles, Red Tail Boas need a thermal gradient consisting of a warm side (90° F) and a cool side (80° F). When your red tail boa starts to shed, you should increase the percentages by about 10 – 20 percent. Red Tail Boa Cage Heating/Humidity? Here’s the minimum dimensions for your red-tailed boa enclosure, based on snake length: Baby (shorter than 2’) — 2’L x 1.5’W x1’H.
The only thing i am worried about is the heat and humidity.
