Ive posted that my rat Willow died today. Im worried about my remaining female, I got her in November of '07, so she is a good two years and a bit. She is still re-cooperating from being sick with Mycroplasma? Im not sure exactly what it was, I mean I know what it is I just cant ever remember the name. Should I get her another friend, seeing as I can only play with her on weekdays for around four hours? I dont want her to get lonely, since she has always had a friend, but im not sure what exactly to do. Advice?
