Is 12 hours too long?

i feed my pixie frog mice and just put the mouse in warm water, wait like 15 - 20mins. you guys are crazy patient.....

LoL.... We're actually impatient. I throw mine out on the counter in the morning before I leave for work. When I come home, they're ready to feed with a quick hair dryer blast to heat the head. Quick and easier then heating water and waiting 15 minutes - for me anyhow...
