Emma has been vomiting a few times a week for a while, I think I mentioned it in another thread a while ago about food/sensitive tummies.

It's not hairballs this time, it's always food. At first I thought that maybe she would just eat too much.

Could this be a sensitive tummy? Should I try a different food?

Also, if so, do I switch all at once or should I do it slowly?

Thanks.
