I got my bp off a 2 month fast a while back by offering live and she's been doing well. Gained the weight back that she'd lost and then some. I tried to feed her last night (she's on a 7 day schedule now) and it seemed like she might have been intimidated by it. It was slightly smaller than the last rat I'd offered. She tried a few different angles and then gave up. Any insight is appreciated.

Just a note; I don't think it's a husbandry issue. Not that I'm perfect (still a bit of a noob) but nothing has changed in quite a while. Temps/humidity are good.

Should I offer a mouse or two next time? Maybe she didn't want to put that much effort into it? (the last rat struggled for some time)

Thanks
