Ball Pythons -
Picture of Adult Specimen
Pros:
1. Manageable adult size
2. Doesn't require special caging
3. Generally docile
4. Low cost of purchase (normals cost around $15 to $50)
(unless you are looking at morphs then the price can go way up.)
Cons:
1. Can be difficult to get eating frozen vs. live
(as can any snake)
2. More easily stressed than boas (in my opinion)
Hogg Island Boas -
Picture of Adult Specimen
Pros:
1. Generally good feeding response
2. Fairly active and receptive to handling
3. All the benefits of a regular boa without the potential 8ft length
(regular RTB can grow up to about 14ft for a female.)
Cons:
1. May require special caging such as Boaphile, be prepared for $200+ for cage alone
2. Costs more to buy a Hogg than a ball python (probably $100-150 for a normal Hogg)
($100-300 depending on m/f size and if pure Hog local or not.)
3. May get bigger than you can handle. Most stay about five feet, but consider how big you want your snake to be. It will be significantly larger as an adult than a ball python.
(Actually realy almost the same size as a BP.(about a foot longer))
4. Requires larger food items than a ball python.
(Eats the same thing/size as a BP(size for size))
Keep in mind: for both ball pythons and Hogg Island boas, females will generally grow larger than males.
