i plan on starting my mouse breeding project next month so i will have feeder mice ready to go when i get my snake in august. i will only have the 1 snake but the mice at my local pet store cost $7.99 ea. (thats $39.95 for mice for 1 month x 12 months-thats $479.40 for mice for a year! way too much in my opinion). breeding just seems the better, easier & more cost effective way to go.
