A quick update, we had a feeding mishap last night. Sushi was ready for the weekly meal, but struck hard and actually flung the rat back out of his mouth. He made a quick second strike and wound up striking himself. He released quickly, and stared the rat down for a while, but apparently felt like it was to blame for the bite, and decided to leave it alone. I checked him out, one small mark where a scale looks slightly out of place, I rinsed it off. Sadly, I had to leave town this morning and won't be back until tomorrow evening, but I'm pretty confident that he is fine, just a little shaken.
