Yeah my snake just hit 500 grams. I think she's gaining weight a little too fast... She just turned 5 months and she's at 503 grams. Every 10 days should be good for me I guess! All the rats I have are at 55-70 grams so they should be big enough for the rest of her life? Unless she grows to like a monstrous 5000 grams or soemthing but I doubt it
