Since may, (when the idea first peaked my interest) i have taxidermied two hopper rats, two mice, and three small rats. All from the same pet store, but bought at seperate times. Each small rat has slipped and none of the other ones have. I have used the same method for each one, am fleshing them to the best of my ability, and dry preserving with borax. I dont understand what is different. Is it just coincidence? It doesn't seem that way. This is very frustrating because i put a lot of time and effort into each one and when they slip all of that work is down the drain. I have heard of stop rot and am not looking for that recommendation. Could it be because the rats live longer? Is there a different method use to kill them? Should i just stop doing rats all together? I would like to someday use roadkill i find, but if i can't even get a rat right, how can i expect to do that.
