Idk what you consider small rats but Ik my 336g killer bee could not take a small rat, at least not without waiting a couple weeks without another meal. I would weigh your feeders and offer 10%-15% of body weight every 5-7 days.
This is how I prepare my f/t feeders. Put rat in leak proof bag, run tap water as hot as it will get, fill tub or pot with hot tap water, thaw until no frozen or cold spots, take rat and hair dryer and heat head for a minute or so while blowing smell into cage, offer rodent while holding it with tongs. If you have a ir temp gun heat head up to 100 or little more if you don't have a temp gun leave hairdryer on head for a minute and a half to two minutes. You can heat the body a little but main focus should be head so the snake can see heat signature and know have a point of aim. This is the method I use for all my snakes and works great for me. I recently bought an ivory off a friend that he tried several times to switch to f/t and kept getting refusals so he kept with live, I tried a f/t the day after I bought him using the method above and the ivory took it no problem. He took a f/t his second feeding also with this method and tomorrow will be his third feeding with me and I'm completely confident he will take another f/t.
If this does not work the first time do not feed a live, wait till next feeding and try another f/t using the same method and if she refuses again don't feed live, try again in a week. Your just going to have to give a little tough love or keep feeding live.
