Many people would like to own them as PETS.
Sand Beast:
Sneake:
Bat Demon:
I must admit, I am one of these people.
( Also, you mistyped snake 
)
Snakes should be a given, especially for RP purposes for Set worshippers. My brother in arms @Necro put out the call for them to be added as Pets a while ago now. Despite being VERY popular (see below), it still hasnt eventuated. I just dont get the resistance.
Sandbeasts and Demon Bats dont look to me like they would repond too well to being domesticated, at least not by humans. But as someone who is always looking to see more darkness and brutality injected in to the game, Im on board. 
Upvoted.
Tell that to my Sand Reaper Queen.
As my Faithful friend and battle brother @Croms_Faithful pointed out with my ancient plea to the developer gods…
I would like to have a slithering throng to come home to!
As for Sand beasts and Demon bats maybe not, seeing their demonic nature 
. But I was riding a mount the whole of yesterday…something that was off the table for long so lets hope we can summon demons with the sorcery update Sand beasts and Demon bats being among those! 
AngelBRZ I looove it!! If only I could recreate that.
Very good.
I have to welcome the new players, then the novice river, it’s easier for me.
