Friend for my mouse

Question
I saved two baby female mice from becoming snake food.  I had them for maybe a little under a year.  One of the mice died the day before yesterday.  The remaining one is eating and drinking, and seems "ok", but because I want her to be happy, and I know they are social animals, should I get her another female?  If so, what age should she be?  Thank you for your help!

Answer
Hi Linda,

First of all, I am so sorry for your loss.  Different mice handle grief differently, so just in case she is depressed, I would avoid getting her a new friend right away.  It can be very stressful to have a new cagemate!

I would actually recommend, when you feel the time is right, maintaining a cage of three mice at a time.  This way, when one passes on, the other two mice can lean on each other and help each other grieve, until you feel the time is appropriate to bring in a new mouse friend.  With that in mind, really any age of mouse would be suitable, as long as they get along in the end.

Best of luck, and again, I am sorry to hear about your loss,
-Tam
