Yeah, that's the reason I tried a live rat pup first... wasn't sure if she would take to a mouse, and I wouldn't know what to do with it all night! I just got home, and the rat was still hanging out with Delilah, so I removed it from the vivarium... he/she is now munching on an old strawberry (all I could think of!) in a shoebox. I so did not want a pet rat, LOL. Guess I'll take the little bugger back tomorrow, but I'm guessing I should wait on the mouse until next week? Oh, and the temperatures were a little high when I got home, so I just lowered the heat a notch.
Please tell us you didn't leave the rat alone in the cage with your snake all day...
