Cool, I thought I was the only one who left camps intact for others. More often than not when I re-visit such places I find them occupied by our fuzzy friends. I have never actually tried to build a kennel to store catches of live rabbits etc. On a lot of rabbit hunting trips I often build a simple debris hut and spend a night or two in order to sharpen my skills as well as get meat for the freezer. I shoot the odd rabbit for eating while there, just to practice dressing small game and cooking over fire and such. I always lay the odd snare as well. The rest of the rabbits I bring home. I have a great respect for that sort of thing and would never harm something I don't plan on eating. (as I am sure everyone on this forum does) So building such a contraption would be something hard to accomplish for the sole purpose of training. It is something to think about should the need ever arise I suppose. I am glad to finally find other people who have the same thoughts as I do. Not many people sit and wonder about what to bring to the woods for a month. Maybe I am not as crazy as my friend tell me I am. LOL
I look forward to hearing more about your scenario.
