Friendly female adult rat in Duncan, British Columbia for sale

Hi. My girl's cage mate died last Tuesday several days after having a stroke. I've been giving her as much attention as I can, but I can't keep it up at this level. She really needs a new companion. I have had pet rats on and off over the past 30 years and I know how wonderful they are. She's about 18 months (a rescue from an overcrowded rattery), was the submissive one of the pair (because of her partial albinoism/poor eyesight, even for a rat)?do you know of any retired does or other lonely rats that need a companion and more adult interaction as well (during the day she is a classroom pet with students)
