Last night I thawed out a rat for my olive. I had a couple of goes at feeding her last night. Each time she struck, but then later I'd check and she hadn't eaten it. I left the rat overnight and it was still there this morning. I figured she wasn't going to eat it and it was time to remove it. As I reached into the cage for the rat she struck at me (missed), so when I picked up the rat I hung it in front of her again. This time she ate it. Bit odd seeing it sat next to her all night. And now I'm wondering how long it would take before a thawed rat shouldn't be fed to them anymore.
