A couple of blood questions

I recently got a sumatran blood python and I'm wondering a few things

At what size do they need a bigger space than a 41qt tub
I see people feed guinea pigs and rabbits, are they any better for the blood than the rats

How old/about what size is your Blood Python? That will better help me answer your question. These guys like to be on the snug side. Especially the younger ones....if they have TOO much room, they can feel insecure which can cause feeding issues, etc.

We feed a variety of rats, and rabbits as we raise our own. We have fed guinea pigs. There is a nutritional chart on Rodentpro's website I believe. Ours thrive very well on all of the above feed.
