I'm in Carnegie. Used to live in Mount Lebanon. Probably going to SH Village Petco this weekend to try and get some rats since I want to start a colony (if they still have them... last I went there all the Petcos cut down to 1 gender, so I'm hoping they have males still and the Petco in Robinson still has females).
I have a male and two females that I can give you if you want. The male is a Siamese and the female is slightly Siamese (but looks more albino). The other is a grey hooded female. Let me know if you are interested.
