I use 9F for all of my rats right now. I have used 6F, 9F, Harlan, dog food, hog feed, Mazuri and Harlan worked exceptionally well. Rats didnt like the hog feed, and dog food made them stick something terrible.
I'm about to try out Kent 19%, and likely order some more harlan.
hmmm.......were the rats so sticky you couldn't get them apart???
