This morning when my husband and I woke up to go to work, both of our cats were fine. This was around 7:45 a.m. He and I returned from work around 3:45 this afternoon and one of our cats was acting kind of funny. He did not come to the door when we arived. This kind of worried us. With in about 45 minutes give or take he started to cough and after doing that off and on for maybe half an hour he coughed up a clear goey liquid. Finnaly about 6 o'clock we were getting really worried and took him to the veterinarian and he thinks he has an infection because he had a temperature of 104 degrees F. I was just wondering what kind of infection could have caused this and what are the chances of my other cat getting the same thing? Also, my husband has been sick with a high fever and coughing up clear stuff so what are the chances of it being the same thing?
