I am having a very hard time with all of this. I lost one of my cats yesterday. He was only months old. He died in my arms on the way to the vet. I thought maybe he was choking on something. I tried to get it out, but it was werid he didn't hack anything or seem in distress. There was a rubber band on the floor my other cat got a hold of and I took it away but now I am second guessing myself. I found Eddie lying on the floor with bad breathing ...all sweaty etc..I picked him up and tried to make it to the vet in time but he died on my lap. He was meowing and I tried to save him but something was sooo wrong. He was died by the time I got him to the vet. The vet said his heart felt swollen and it was mostly likely a heart attack. he was convulsing at the end. A part of me feels sooo guilty like I did something.....I feel sooo bad...I tried to get him there in time.
