So I have had my bp since october or slightly earlier and shes getting bigger. I want to say shes about a inch in diameter at her biggest and about 2 feet long. I dont have a scale and I really dont know how big around small rats are but I know for a fact that she isnt full after one adult mouse anymore. I hope one of the more experianced people on here can tell me if they think shes ready for a small rat. I also dont have the funds for a scale atm and its way to cold to take her anywhere to weigh her (even though taking my snake some where to get wieghed seems obsured).
