Zara, I'm so sorry to hear Tia is not doing well. Prayers are on the way.

I'm about to be a rat mom for the first time, my boys were born about 2 weeks ago and they come home in the middle of next month. From all that I read, short life spans tend to be a curse for the rat mom. Even though her life seems short, it is in fact a full life for a rat and no matter the outcome, that should bring you comfort.

Zara, you are very mature, not just for your age but for an adult, and if it comes to you making that very very tough choice I know you will choose the right thing.
