We brought our nearly 3 year old cat to the vet today as he hadn't been eating his food, just small amounts here and there. I thought it might be his teeth as he was licking the juice from his wet food. I noticed he had definitely lost weight also and was lethargic. Vet told us he is severely anemic and could have kidney failure. He had lost 25 percent of his body weight from last year. I am in total shock and feel such awful guilt. How did i not notice it was so bad...He got bloods done to see what's going on but apparently there isn't much that can be done and looking like he will have to be put down. I am so devastated. Has anyone experienced same with their cat? He was absolutely fine but just the past few days where he seemed to have deteriorated quickly.
