i have a cat she was having vomiting and less active for 7 days. Previously, she was ok but now again she is vomiting and not moving as much.

Depending on what the veterinarian finds on physical exam, they may need to perform additional tests such as bloodwork or take xrays if they think there is a foreign body.
