She looks underneath a rat!
My tiger girl ate rats for about a year and then decided to become a mouser (my only one). I have stubbornly tried to get her to take a rat again for quite sometime. No matter the size she won't take it. But as soon as a mouse hits the floor she's on it.
After skipping a feeding period so she would be good and hungry, I tried again last night. I selected an appropriately sized rat, dimmed the lights, pre-scented, and dropped the very calm rat in with her. After a few minutes of nose tag and getting to know one another the BP forced her head underneath the bewildered rat who just sat there! She was obviously looking for babies (mice)!
