So, I have a guinea pig, whom I love very much
But she isn't doing too well
She's about 4 1/2 y/o, very skinny, her fur isn't as thick as it should be, her skin is VERY dry in some areas (belly, ears, nose), and her pellets are very tiny and mushy
Her 'sister' passed away only a few weeks ago, she had a similiar skin problem only much worse, and began having troble walking...I've been using a witch hazel-water-listerine mixture to spray on, which supposedly kills mites, but it doesnt seem to be helping--

what can I do for her?? Are there any foods she should be eating, and is there away I can bring her off her pellets and move her onto all fresh fruits and veggies?
