My youngest rat Sonny is very skiddish,the only time she really feels comfortable being pet is when she's inside of her cage. My other rat Shade took to me and my girlfriend much faster but she is a more exotic looking rat. Sonny is white with red eyes and the other rats she was with were very antisocial. I was wondering if Sonny being a plain white "lab rat" was being more bred just for being a feeder rat and not for being a pet,maybe inbred or just not handled very much? Also all the pets at the Petco I got Sonny at were pretty boring and didn't seem to interested in attention and there was only one person at the store working the register unlike the Petsmart I went to to get Shade where all the animals including the birds were very playful and there were many people working there who played with the animals alot. Do you think her trouble adjusting to people is caused by the lack of attention or poor breeding at the store?
