I had a one year old cat that passed away yesterday. I have no clue as to what could have caused its death. It hadn't eaten in 5 days and constantly vomitted. I didn't have the money to take it to a vet. It lost a lot of weight and wouldn't eat. It seemed to lose all energy and life in it. Finally it just stopped breathing yesterday. I would really like to know what could have been wrong with it. If anyone has any ideas please let me know.
