Last night I put a bowl of kibbles into the rat's cage and poured a little fresh kibbles on top. I completely forgot that the bowl already had some kibbles that had previously been wet from some baby food 3 or 4 days ago. There were fresh kibbles in the bowl too. I took out the bowl this morning to fill it, and when I looked in I thought the rats had just pushed some squished poop into the bowl. I kept looking at it, and realized it was black, molded over kibbles!!!!! I'm scared they might have eaten some.. I can't believe I forgot about it or didn't throw it away before I went out of town a few days ago.. Everyone is acting ok now.. and there were fresh kibbles in the bowl as well. I'm hoping no one ate any.. Should I do anything? Or just wait and see if anything happens? I feel really terrible....
