I'm in the process of trying to convert Oreo to f/t mice. I fed him a live hopper yesterday and then thought I'd try a f/t one while he was excited. He didn't take it so I heard someone mention that sometimes it's a good idea to leave it over night.
Well, I forgot to take it out of the cage this morning, and when I got home from work..... well, you know; an overwhelmingly bad smell permeated the house.
Airing things out now but it was pretty bad there for a while.
