My bp has been on live rats but I couldn't find any around here readily available. So the lady at the pet store gave me a free fuzzy mouse just to see if he would take it. I am 98% positive it was thawed, and I sat it in warm water before offering it to him. He took it and squeezed for a while then just let it go and moved away....does he not like mice or do you think it was not thawed completely?
