its DEFINATLY a good way f thinking buff, and it can be a realy good skill to have when doing a colony, especially when you have a breed where all the does look alike lol
its a good way to make sure you"got everyone" during your planned breeding time, and saves youa good 2-3 weeks in waiting should she be barren as you can rebreed her right away rather than waiting and hoping...
its not a big deal if your breeding for pets to miss a female ect, but when your reying on the meat its always good to be able to rebreed asap should one "miss"
