My cat (12 yrs) died suddenly this week. He was seemingly healthy. No symptoms of illness. He was fine and then made sounds as if he was having a hairball (heaving sound, he fell on his side and continued to struggle to breathe. It lasted about a minute or so and then he died.
Today my neighbor (house close by) said she sprayed ant killer around her house and I had my side door window open. I don't remember seeing her there when this happened but am looking for an answer to my kitties sudden death.
