I found it in the middle of the cage in her water bowl. I think she had done it somewhere around 5 to 6 pm shortly after I left for work. The cool side temp I spoke of was belly temp according to the infrared temp gun I use. The ambient temp is usually around 80. From other situations I have read about leaving her for a while before eating is what I figured I should do along with only feeding her one mouse. After that if she vomited again I figured it would be time for a trip to the vet
