Looks like she had some stomach infection
which has improved but the intestines are still sensitive now.
If she is constipated you need to address it.
Do not give her aerated drinks as they may worsen symptoms.
Worthwhile getting an x ray abdomen done to look for intestinal obstruction
which can cause recurrent vomiting
with pain. A cat scan of abdomen will give final answer but involves lot of radiation
exposure hence advised only when its necessary.
hope this answers your query.
wish her a speedy recovery.
