My 9 cats won't eat
All of my cats eat together every night. They usually run to the food the second they hear it. Now, they barely walk in there. They eat a little bit at a time and they're finished. All of them are throwing up. Sometimes they spit up, other times they vomit large amounts. Recently, one of our cats had surgery, so we had her on a wet food diet in another room for a couple of days. I don’t know if they're upset about this change or what. What is happening? It's been about 3-4 days since this all started. The second day, we woke up to a ton of vomit on the floor. The first night, we tried to feed our surgery cat, she didn't like it, so we gave it to the other cats. After that, they've all been sick. These cats are a couple different ages: 2 are a year old, 3 are two years old, 2 are 5, one is 15 (surgery cat), the last one is 8. Please help. Currently, we’re waiting to see if they get better on their own but if not we’re going to have to take them to the vet. I just don’t understand how all of them are affected.
