Woosh! My cat landed on the couch next to me and began running around frantcily. I knew instantly something was wrong. Sassy was twitching and running from spot to spot and twitching some more. Her eyes were wide as if there was no light in the room even though it was quite light. She also began hissing and hitting me with her paws when i tried to touch her.I felt my cat and stickey smelly liquid came off her back and on to my hand.
