Last time I bought mice, I was given small rats instead of mice. I figured I'd see if my guy would take them, and sure enough, he did, no problem. But when I went back to the pet store, I looked at rat prices and they were freaking outrageous. $3.99 for a small rat pup, when adult mice are $1.99 and way bigger. He'd need 2 rats per sitting, at least. If I'm going to feed multiple prey, it's going to be mice, because I'm not made of money.

After feeding rats for 3 weeks, I fed a mouse last night. Mine had no problem switching back to mice though... guess he's just not as finicky as some of the eaters here.
