well... I wanted to get a new rat so my lucy would have a lil buddy to hang out with...buuut...well..the last rat we got from there died...im not sure why it died becuase there were no signs of her being sick or anything...she was acting just as cheerful as she always had..and the next morning...we found her dead. And ive read that petco often sells defective rats, and my dad suggested getting one from petsmart, but is there really a diffrence? im not sure there are shelters near me that have rats, and I don't know if my parents will take me to a breeder to get one, but I really don't want another rat dying on me
