I want a Burmese but am scared of having one now that all the stories I have heard. Just a few questions:

How big can Burms get in 1 year? (I have heard anywhere from 10-12 is that true?)
Are they agressive? (I would mostly be feeding the Burm(s) in a seperate cage but here they are always looking for food.)
What sized enclosure is good for them?

I am doing research but am hearing different from different people. Thats why I asked my second family for help!
