Is she ready for bigger food?

My boa is now just a little over one year old. I have been feeding her one frozen fuzzie on a weekly basis. I am beginning to think though that she needs something bigger. The next 'size up' at my local Petco seems to be a frozen baby rat... but is this too big for her? I don't want to damage her by her eating something that is too big. Is she ready for bigger food every 10 days, or should I still wait?

Thanks for your help!

yes indeedy

As long as the rat isn't larger than her girth, she is ready for it...
