Totally off-topic but our donkey, Jackson, was jonesing for dogfood. If I really needed him to go in the field, all I had to do was shake some kibble in a can and boy - did he come running. (He liked French Fries too - don't ask)
I cracked up when I read the list of things you tried. Holy Moly what a smorgas board.
RIP little rogue mousie.
