My little Lily is almost 3 years old and is my favorite thing in life. Last night we noticed that she was breething fast. Today she is worse. Her breething is very labored. We have three adult cats. All of them are inside-outside cats. There are fox in the nieborhood. Lily has been acting fine. She doesn't act sick or uncomfortable. I am so very worried about her. What should I do? More-She has had couphing spells ( where she will jump onto the floor and turn her head back and forth gag-couphing for a few minites) cince she was a baby. She has had 3 of these attacts since last night, that I know of.
