What a relief and good news! We're calling the vet today on Boo. She seems to be throwing up daily and it's not hairballs. I don't know if she's gourging herself only to throw it up later (cats rescued from the wild tend to do this for sometime until they realize food is provided on a regular basis) or if there is a problem with her. I did feed her a very small amount this morning to see if that may be the problem.
