I'm finally mentally ready to do the feeder mice thing and I think it'll be a good way to get some bone into my kitties since two of the three won't eat whole bones yet. Here's my dilemma.....SHIPPING! It's +/- $40 everywhere I've checked! (I do plan to grab a few frozen mice from the pet store before I place an order to make sure they'll eat them.) It seems like I'd have to order bags and bags and bags of mice to make the shipping worth it! Is that what everyone does or is there some cost effective alternative?
