Hello, today I was meant to go to the vet my 10 week old kittens 2nd vaccination, however, this morning I saw her vomiting and diarrhoea, so instead, we talked to the veterinarian about it. Recently we've been slowly changing her dry food to something better so we suspect that may be the cause of the upset stomach, the veterinarian gave us a prescription diet to feed her until she feels better. Once I got home I put some of the food there for her to eat but she smelt it not sure if she took a bite or not but straight away proceeded to vomit out saliva and some white saliva looking thing. Was wondering what I can do, should I just leave the food there hoping she will eat it?
