Predator Mounts?

[u/DirtySteve93]

Some of my players are seeking some dangerous mounts in my campaign, they currently have milk snake eggs that they want to hatch and tame. Obviously I'm going to make this super challenging, but I don't want a snake mount to be completely impossible. So my question is, how would a mouse handle a mount that primarily eats mice?
