a friend of mine emailed me today to tell me her cat had to be put down this weekend. She has recently moved to a new home and I think has started to let her cats outside (not sure yet as she hasn't emailed me back about that but they were outside at her previous place so I am assuming for now). She had 4 cats, two were brothers and one of those is the one that died. I want to tell you what the symptoms where that the cat had and if anyone has ever experienced something similar and if it was positively diagnosed. I am concerned that the cat may have been poisoned. The cat, Bailey, started to vomit almost non-stop and the vet had to give him a shot that calms the gag reflex but it did not help at all. It became worse and worse and he had to be put down by recommendation of the vet. Now her email was not very detailed and I don't know if the vet had given her any idea of what could have caused this but the last response I recieved from her she wrote that she did not know what it could have been. If anyone has any knowledge on poisoning or the symptoms, I would greatly appreciate it. I fear that her other cats, if let outside, might have the same fate.
