My BF just called me and said Marley, 5mo, puked up rice and onions. I have NO IDEA how he got into it!!! Im assuming he ate it this morning because thats when he puked, but I can't be for sure...it could have been last night. Aslo, I don't know if the onions were raw or cooked. I have read that onions are toxic to cats and can cause anemia. I don't know how much he ate but the BF said what he puked up could fit in the palm of your hand. What should I do? I made the BF make Marley drink some water. He said he is acting fine, but he didn't eat any of the food I left for him this morning. Any advice is much appreciated!!!!
