So we adopted Hollis at the end of May. She had not ever really been on any wet food, so we started trying a few here and there to see if she liked them as we read it was important to have lots of moisture in their diet. She projectile vomited anything with fish and beef, so we have since stuck with chicken. She gets wet food once a day and typically only about half a 1.5oz can. She is a tiny girl at 5lbs. Every so often, as soon as she finished eating, she vomits, like within seconds of swallowing her last bite. Yesterday she vomited up her food, then vomited up clear/milky liquid about five more times. She doesn't seem to feel bad, but I'm not sure what is causing it. It only happens every couple weeks. She is not food driven at all, so she gets very little treats, and free feeds dry kibble. Is this something to be concerned about?
