Is my ball python underweight?

And yeah gaining only 10g in 2 months seems slow weight gain. Feed every 5-7 days. And as i've noticed they gain weight faster on rats.

Also here's a chart of prey size for mice and rats ;) By the weight you specified either he needs rat fuzzies or mice hoppers. He could even munch on a smaller weaned mouse.

Well, when I weighed what I just fed him, it was about 8g, so it was probably a hopper? Im not sure, they have slightly different classifications of size at ARC

I find it stupid and sizing by some prefix. Probably every breeder defines this. Here in Slovenia small rat would be from 100g on etc. But 100g is 100g everywhere ;)

Let's rather say you fed just fine. It's in the 10-15% "guideline". But do try to switch to rats. You can also try offering another mouse after the first one. If they're fed they won't take it, but if still hungry they munch on more than one happily :P
