I am not sure. I am feeding what the pet store told me to when I bought her -- so I may not be referring to the correct name (that is very likely). They are small white mice -- they do have fur so would that be a pinkie? I am not good at sizes but she is about 23 inches long and the mouse is probably about 2.5 inches long not including the tail. I am trying to learn all the terms. The pet store told me to feed her one every 7 to 10 days. This pet store is creditable so I am thinking they gave me the right size but I may call.
I do feel that the wound is may be an old bite mark -- it seems like a scar would be healing on us. I just wanted to be sure! Honestly that book has made me paranoid too.
Still learning here -- and just want to ensure her comfort.
