Hey there!~ Good to hear from you again and so good to know that your guy seems to have outgrown his throat issue!!!
When my yearling boas were 225g I was giving them weanling pups every 7 days. I get my rats from The Mouse Factory and their rat weanling size is 35g.
Those yearling boas are now in the 700+ gram range and are eating small rats that weigh 55g.
