Striking and missing is sometimes a sign that the prey isn't warm enough. Try hitting the prey item with a blow dryer for a few mins after they're warm. Focus on the head area.

If you do leave the prey item in overnight and they don't eat, I wouldn't refreeze, I'd throw it out.

As for the zero interest, perhaps try mice? I had a few that came to me eating rat pups then decided they only wanted mice with me so I had to go through the whole process of converting them back to rats. Ugh then I had one who was on rats just fine then all of a sudden only wanted mice and is just NOW back on rats.

They can be fickle little creatures sometimes.
