My Kenyan sand boa

[Spat]

Hello,
this is a pic of MARDI GRAS my kenyan sand boa!
It's a male of 3 years old.
He is small but fat!! I have his since 3 month and He ate just 2 times since acquisition (1 frozen hopper mouse each time).

It's maybe normal because is fat?? What do you think about this? Do you think that I should try a fuzzie live mouse?





Thanks!
