I, against my better judgement, bought some mice from Petco to start a small breeding colony. I purchased 1.8 and have them in a large rubbermaid. I am not new to this but not an expert either. I added a little vanilla to the water to cut down on the smell and am feeding a small animal feed for everything from rabbits to mice according to the bag.
After a week about half the mice look just about dead, with their eyes nearly shut if not totally shut and barely moving.
I replaced their water as I know sometimes they won't drink with the vanilla in it. I also added some dog food to maybe see if that was the issue.
I lost two for sure, they we suffering too much so I dispatched them.
Any thoughts?
They were housed on carefresh.
