One of my cats has been vomiting her dry food only periodically. She is fine with wet. Wet food is Fancy Feast which both my cats love. She (the cat) is under vet supervision and her vet is okay with me switching out her kibble. Is Science Diet or IAMs for sensitive stomach okay? Just need some recommendations for something not too expensive. Also, please keep in mind I am a senior on a fixed income with a part time job. So I have limited income and can't afford some of the expensive brands I have seen like Tiki Cat. Especially with 2 cats it would need to be something both of them could eat that I can also afford. Thank you for any help.
