My one year old cat threw up twice on August 23rd, but she was not acting lethargic and was still eating and drinking normally so I thought she maybe threw up because of a hair ball. She threw up again today twice, with one being a very small amount. She is not acting lethargic and is active and playing. She is also drinking normally but she has not eaten as much as normal. Both times she threw up when I was not at home. She did start eating when I got home today though. I also free feed her but haven’t had issues with her vomiting due to eating to fast or vomiting in the entire time I have had her (one year). I’m not sure what the cause of her vomiting could be.
