I'm glad that Baby came back home Sara. I can imagine what you went through.
Furkids know when they need to fast and will do so on their own. In the meantime, I would concentrate on giving her healthy food and let her eat at her own pace.
Would it be possible for you to get a colloidal silver generator? This way you would always have collooidal silver on hand and at this point it would be of great benefit to Baby.
Okay....... The two above foods that you are considering are junk, no better than Whiskas. First option, I would give Baby raw food..... Second option, homecooked, but only meat, nothing else. And I would seriously consider the BARF Diet.
