My cat recented died, three days after receiving her annual exam and shots, vet said it was not a reaction to the shots. Does this happen? She was very lethargic, then choked, vomited bright red blood, staggered out the front door and collasped within 5 minutes. I would just like to know. Vet said she was probably poisoned??

That is terrible! I am so sorry for the loss of your cat. I don't know what could have happened but whatever it was is terrible!

I'm so sorry! Had she eaten anything around the house or outside that she wasn't supposed to? There's so many things that are poisonous to cats, such as lilies and a ton of other common house and garden plants. :-(
