One of our four rescue ROIs has been unusually quiet and inactive today,
she seems uninterested in food and looks almost red eyed.
DH had to pick her up to put her to bed long after the others had gone in.
I'm thinking she's on the way out, but we've only had them 3 months so can
it be old age? She has always been the quietest and most nervous of the 4.
any advice would be much appreciated.
