My farrow cat was really energetic until this morning. She lies around and can't lift her back end she is breathing really fast and hard with a crying moaning meow. She has dialed pupils and won't open her mouth for me at all. She won't eat or sleep. She seems to get worse every hour. Please help she is only a year old she has a long life to go yet. I also got a poinsettia plant and I think she might have eaten the leaves. Is this poison to cats?
