never put a frozen feeder into hot water.
Try this...
Have a small bucket or bowl ready. Sometime early afternoon, take out the FROZEN rodent and put into that small bucket bowel with COLD water.
Leave be until late evening.
Late evening, drain the cold water. Add HOT water. Not burning hot, but def. hotter then very warm. Since you are feeding tiny mice, you don't have to wait so long. Give it 5 minutes, drain water, fill again with hot water. Wait 5 minutes, drain water, fill again with very hot (again, not to the point of hurting your hands, but hot) water.
So you do this 3 times. Drain and refill.
After the third time, take out the rodents and roll up in a few paper towels and carry to the cage. By the time you get there the paper towels will have absorbed most of the water. The rodent should feel quite warm.
Offer rodent. Make sure you do this late evening or at night.
Your baby might need a cage that has less deco. Just stuff on ground. Several hides, dark substrate, dark around the cage. Sometimes you have to go to a smaller container, but try the other tricks first![]()
