Expert Tip: Different breeds are susceptible to different illnesses, and it is important to be aware of what health risks your pet can have.

Red Tail Boa Diet

In the wild, Boas are ambush hunters, waiting patiently for their prey. They use their muscular coils to capture and constrict their food, which usually consists of small mammals, juvenile birds, and even lizards.

Being kept as pets, Red Tail Boas do not need as much body mass and therefore can feed on smaller prey. They usually eat rodents and should be fed on a regular schedule, with the size of the prey depending on the size of your snake.

While your snake is under three feet, feed them two mice weekly. Once they become larger than three feet, upgrade them to one rat and reduce the feeding to once a week.

At six feet in length (and larger) feed them one to two rabbits once every two weeks. Depending on their age. size, and if they are maintaining a healthy weight, your snake can be fed less frequently.

Red Tail Boas can become underweight or overweight, so it is important to pay attention and keep track of your snake’s growth, weight, and body mass.

Red Tail Boa Enclosure

The natural habitat of the Red Tail Boa has a high humidity level, which needs to be replicated inside its enclosure. Humidity around 60%-80% is best for your pet snake and putting a light above its water bowl will also help maintain the high humidity. If you use a screen lid for its enclosure, be sure to use a pegboard with lots of tiny holes.

It is recommended to use humidity gauges to monitor the humidity level inside your Red Tail Boas habitat. While first setting up the cage, watch how the humidity rises and falls, so you can get a good understanding of how to monitor and regulate it. Use a UVA basking bulb for the lighting, and cypress mulch as the substrate.

For the tank type, it is best to have one custom-made or get a plastic tub. Make sure that the size is 6 x 2 x 2 feet. These large enclosures can cost around $500. While baby Red Tail Boas can be kept in a 10-gallon aquarium, due to their quick growth rate, it is recommended to start with a 20-gallon aquarium.

Once they reach a length of four feet they should be moved to an adult tank. There are some varying opinions on the appropriate terrarium size for a Red Tail Boa (just like red claw crabs).

The main thing is to make sure you have an appropriate amount of space for your snake when it reaches its adult size. The rule of thumb is to get an enclosure as long as your adult snake.

Often people get enclosures that are 6 x 2 x 2 feet though enclosures this large are difficult to find and are usually custom made. Plastic tubs are recommended, as they can retain humidity better than other terrariums.

All snakes can be escape artists, so it is also important to make sure that your Red Tail Boas enclosure has locks or latches to prevent this. If your snake escapes, this can be dangerous for the snake, as well as any other pets or people living inside the home.

Expert Tip: Red Tail Boas are constrictor snakes and feed on small prey mammals. If you also own a bird, cat, rabbit, or a small dog, they could be at risk if your snake breaks loose.

Cage Set-Up

Red Tail Boas need a cage that has a temperature gradient, with the cool side and ambient temperatures set to around 80 to 85 degrees Fahrenheit. While the hot side is set around 95 to 100 degrees Fahrenheit A UVA heat-emitting bulb can be used to create a basking spot for your snake.

Snakes do enjoy having a hiding place, so place a hide on both sides of the cage so it can be comfortable in both hot and cool areas. The next thing to consider is the substrate. The most common bedding used is Aspen, but Cedar mulch is more highly recommended.

It is important to remember never to use cedar or aspen shavings, as they contain oils that are toxic to snakes and other reptiles. The last thing for the enclosure is water. Your snake will want to soak, so choose a bowl that is large enough to fit your snake. Monitor the water daily and keep it clean.

Does a Red Tail Boa Bite Hurt?

Red Tail Boas are well known for their docile temperament and are not usually aggressive. Most bites that have happened are usually due to mistakes made during feeding. A bite from an adult Red Tail Boa is incredibly painful, but not lethal, and there are many ways to prevent bites from happening.

You should first learn how to handle a snake, especially a large one. When holding a snake:

  • Always support their body weight
  • Make sure it is awake, and aware that it is you who is removing it from the enclosure
  • Snakes are head shy. so avoiding tapping or grabbing their head

Temperament varies from snake to snake, and their age also plays a factor. Red Tail Boas can be quite nippy when they are young and not used to being handled. Their bites are often quick and over before you realize what it’s doing.

Bites from adults are painful and can be severe, depending on the location of the bite and how you react to the situation. Red Tail Boas have sharp teeth that curve toward the back of their mouths.

If they bite and hold, it is suggested to remain calm or you could risk further injury. Often your snake will release on its own, so remain calm and wait it out. Once your Red Tail Boa releases you the wound should be cleaned and treated, as snakes carry plenty of bacteria in their mouths.

Expert Tip: Never handle your boa while it is shedding, as it may not be able to see very well and could become startled. And as with any animal, never handle your pet snake while it’s feeding.
