This is my first visit to this site. I am trying to find information or advice about my cat, Joy. She is 3 1/2 years old. The last week she has been drinking LOTS of water and occationally vomiting (which is very watery). Can cats get the flu? Should I be overly concerned? She is normally a very healthy cat. She is an indoor cat that has been declawed and fixed for 2 1/2 years. Thank you for your time!
