Hi, welcome to PT. I have two rats named Oliver and Tobias. Oliver is a velveteen agouti Irish and Tobias is a satin seal point siamese. One day I would like to have a reputable rattery and rescue. Congrats on your new addition --- though you really should have quarantined her. Having 13 rats I would imagine you have done enough research to know the deadly diseases that pet store rats can pass on to your other rats. Please don't disregard this sad fact. Hopefully you'll remember this next time! It's better to be safe than sorry.
