Was the Y in the center of her chest in between her upper arms? I can see she has white feet also, therfor you had an irish! Good marked irishes are hard to come by, consider yourself lucky!;) I love irishes. Sorry to hear about your ratties. If anyone wants to get a look at some of my rats, go to my profile and click on my webpage. You can see cute little rittens there too! :D
Oh ya for those who don't know what a ritten is, it's a baby rat. They are actually called kittens but some breeder (like me, hehe) like to call them rittens. R for the rat. Get it? :p
