Yeah Artgecko, it took me a few tries to get the cervical dislocation thing down. Even now with big rats, it is a pita. I'm about 50% on it working the first try which makes me feel horrible when I do fail. The smaller ones are easy as they have small necks and it breaks easy but those big ones....... CO2 is the easiest. You could also do F/T but for me, I look at F/T as a tv dinner and a fresh killed rat as home cookin! Yes I'm probably weird for thinking like that but how I picture it lol
