Weird Behavior

Phoebe's been acting weird the last couple of nights. Spending most of the night upstairs instead of coming down and sleeping with me and Sabrina (I'm hoping it's just 'cuz it's rather chilly in the basement.)

Last night though she woke up her Grandma to go potty!
In the several years that we have lived there she has never done that!
AND I guess she wanted to SLEEP in her Grandma's bed! (Mom obviously said NO to that one!)

I'm so glad she is going to the vet tomorrow. These weird behaviors are making me worried.
