Pet wise......I would say go with a Dumeril. I think they are mellower and make better pets.
Both animals are fun though. A blood is a little more demanding. If you are looking for a challenge......A blood is where it's at. They can be more tempermental. Mine would hiss at times. But, the funniest thing was how it would thrash. They are also VERY strong animals. They may look cuddly and fat. But, they are not. They are quite strong and strike quit hard. I was lucky to never have been bit. I would take a boa bite any day over a blood. But, that is just me. You also must pay attention to humidity levels more. This takes a little more work. And, you have to make sure that you have a good cage that hold humidity well. They are fun though. I use to call mine Fatty Fatty Two by Four. She was a great animal. Full of personality!! I use to lay on the couch with her and watch movies. They do not like to be out in the open. So, she would push herself under me and hide. I weigh 235lbs. And, she could make me move.
One big thing I learned from another forum member is that they do not like to be held per say. They are much more comfortable sitting in your lap. When mine got big enough it got quite an attitude and would thrash when I was holding it. It wasn't until I learned to sit down with it....That it mellowed again. A fun pet to own. But, they are a challenge. Not a mellow boa type pet though.
Dumerils are great as well. You just have to find one that is a good feeder. My girl was a monster when she matured. She was really mellow. They are also a terristorial type snake. They feel much more comfortable on the ground or in your lap. I use to cuddle with mine and she would fall asleep on me. They are very unique looking as well. When I had my albino and other morphs I had a friend come over and marvel over the Dumeril compared to the albino boa. I would say a Dumeril is more of a pet type snake. Different, yet undeanding. I kept my Dumeril just like I did my boas. I raised the humidity a little for her during shedding. Where my BCI's would have mo problem she would not have a good shed. So I misted her during her shed cycle.
Check out this link. Mike's a good guy. If I were to get a Dumeril again. I would get it from him.
Hope this helps.
