My cat jumped from her chair where she had been sleeping about a week ago. She walked a few steps then just went down on her side. I went over to pick her up and noticed she was limp. Her eyes were totally dialated. She tried to move her arms but was basically limp. She was breathing. I was afraid she was in pain as she had been sick and getting very thin over a period. No one could tell me what was wrong. Did she have a stroke? Was it shock? I put her down because I didn't want her to suffer anymore. I love this little kitty so much. I miss her and would like to know what happened.

You need to talk to a Vet.
