Right...So I tried a rat... even tried heating the head with a blow dryer. No go. Tried a mouse. He did not strike instantly (as he did last time I tried a mouse) but, he struck, and ate. about an hour later (checked on him 15 and 30 minutes in, he was still working on it) I offered him a second mouse. he refused, I didn't push the issue (I offered, he refused, I removed myself from the situation). Then I see, he regurgitated the mouse he ingested. This breaks my heart. I will weigh him in the next day or two, and possibly get a picture. It's just so very frustrating. Everything is pretty much the same since he got here :-(
