D.M.
I was thinking what every one else said. Her diet isn't sufficent and that perhaps she has worms. Worn treatment is just one pill, all it takes is a fecal sample to be looked at the vets office. Something you want done regulary with small children around anyway, if you are not already doing it. I'd get the glands done again as well and ask the vet about suggestions for a high quality food for her. I hope you can get this cleared up so your kitty doesn't loose her home.
