I was just asking about this same topic a couple days ago. Last night was my first attempt at switching from f/t mice to f/t rats. Went through the same preparation techniques (thaw in fridge from morning to 7pm, take out and sit in front of cage until about 10ish and then hit w/ hair dryer). My BP was already out around 10ish which was a nice surprise but he quickly jumped back when he saw me. I presented the rat w/ tongs and he seemed very interested. He struck once and missed (only the 2nd time he's struck since I've had him). I continued to dangle the rat in front of his hide and he continued to examine it and flick his tongue. I was pretty psyched because I felt like he was going to go for it. After 5 -10 minutes of holding it, I decided to let it lay and walk away for the night. And just like every other feeding, it was GONE in the morning. Amazing how great a feeling it is!!!!!! He even poked his head out this morning of his hide as almost to say...."any more?" haha....
