If she's eating and drinking thats a good sign... Pixie went into a serious depression when I brought Paris home.. lasted weeks.. she slept, no toys, no trests, no bully sticks... nothing! she was just depressed! And she would have nothing to do with any of it.... I thought she has mono!!! lol
But she was fine... Her temp was low for that first week and then was normal.. my vet said stress. I took her in... I thought she had some sickness!
But it turns out she just had a grudge and was pooped.
