What i said about feeding problems is a fairly widespread problem with that species, they can be picky eaters and many people have problems with them eating even yourself. I see them go off food for periods and i do see many posts not just here of “help! My ball python wont eat” of course it could be just that there is a higher prevalence of ball pythons and therefore probable that there may be more instances of problems.
Ball pythons require a consistent humidity wheras rosy boas do not so long as it doesn’t stay over 60 for long stretches. Its much easier to maintain a species that is native to California than it is trying to create a southern African environment. Sure theres breeders and keepers of balls in california but most breeders should know how to properly maintain correct conditions same with most keepers.
I haven’t met a retic yet that wasn’t very defensive unless you work a lot to desensitize them to you. Also a retic besides their gianormous size have a potential to seriously harm a person, a rosy (even my large male have a small head so little chance of doing any real harm if bit) yes some baby Rosys can be nippy but many baby snakes are more defensive but in general they are pretty docile, they are also a slow moving snake, unlike some other varieties, balls tend to move slow too.
While they may have similar temperatures around 85/86 California doesn’t have that humidity except artificially which requires monitoring and work which for a beginner can be a bit more difficult.
True many pet stores especially big box chains tend to know very little about the animals they sell.
I haven’t heard of a rosy boa with an eating disorder however that doesn’t preclude the possibility that there may be Rosys out there that don’t eat. I know none of mine have ever had a problem and nobody i know that have Rosys have feeding issues.
Balls are a beginner plus animal, it helps if you have had experience with animals that are similar needs.
Honestly my Rosys never even use the heat pad, they may once winter hits, but then again they will be in brumation where i will drop the temperature. Of course you should still provide a hot spot of 85° just incase they need it. My room is about 83°+ every day so they don’t seem to want the hot spot.
Yes everyone has their favorites and they will all convince you of their favorites, but most are only willing to tell their positives and not be too particularly about speaking of negatives.
The OP said they had a child and pets such as a dog, so one has to consider factors such as safety. I wouldn’t even recommend a regular boa because of the size they can attain.
