Corny is very pretty! Now to get his appetite loss figured out. I'm assuming that by "large mice" in the quote below, we're not really talking about adult mice? Feeding twice a week sounds like a recipe for regurge, unless we're talking about pinks/fuzzies??? (how big & how old is Corny?)
"...she said i should start feeding two of the large mice i have every 7 days, or one mouse twice a week. when i mentioned buying bigger mice she actually advised me against it."
