I'm sure everything is fine but I'm a little worried about my new baby. I just brought her home yesterday and she's thrown up a little bit 3 times within 24 hours. It wasn't a lot of throw up, but I get worried easily. It was liquedy and yellow. I think I could see a little bit of her food, but I'm not sure. She's a 4 month old Himalayan. She's been drinking water normally but she hasn't been eating as much food as I think she should. I bought her Purina kitten chow and she had been previously fed Kirkland signature brand cat food at the shelter. I'm hoping she is just not used to the food change. Plz give me some insight. Is this normal? If she continues to throw up when should I call the vet?
