moms cat 14 years old looked fat for a while now. At one point she seemed a bit congested but that seemed to clear but she kept drinking tons of water, Today went to moms who is ill with dementia, Her cat would greet me at the door and I would give her and her brother a snack.. She hid though i noticed her dragging her rear leg... Called the vet.. Perhaps a leg pull... Then I noticed she was trying to walk room to to room and try to get comfortable but her breathing was awful.... I called the vet and said this looks serious. She took an xray and said many things going on... The xray showed tumors around the kidneys and her intestines were being shoved down. Plus an enlarged heart which was causing her not o breath . What was more odd I kept telling my mother she is very overweight so stop feeding her so much as my mom has dementia... ONLY to find out when I told the vet she is very overweight in reality she was not!!! she was distended from the tumors. She would drink tons of water and ate alot.. I just thought my mother was over feeding her.. But it seems her beloved cat had a bigger issue at hand and even detected early may not have been good enough. Heart failure is heart failure and she hid it well till today. I had to put her down as the vet said she never would make it through the night... I feel so sad but it had to be done. Mom with ALZ I tried to tell as I was crying but it was so hard for her to understand... Now the cats brother is all alone.I fear for him.. Only solice I have that her cat was trying to tell me something "get me help" I felt it in my GUT.. But No matter how good or bad it is... IT HURTS 14 years and now her brother has no one..... I am blown away!!!
