Spoke to the vet that administered the meds and they told me the corrict dosage for a 450 g chin is.20 cc. So glad I haven't been giving the complete .4cc since I thoughg it seemed like a lot. Ivory isn't eating as much as she would without the meds, but she's still eating so I'm glad about that. She ate 2 cheerios this morning and I saw her eat her Timothy hay last night. I don't know about eating her pellets though, haven't seen much of that. Might pick up some critical care tomorrow just in case. I guess it's available at most pet stores?
