Can anybody tell me why some cats get very thin when they are old? I have 2 very old cats, they are both deaf and both extremely skinny. One of them is in perfect health, he is just very thin. The other has recently been diagnosed as diabetic and so I can understand her thinness. Them being skinny does not bother me, but unfortunately, my neighbours are worried about them and keep feeding them because they think they are under fed. They both eat loads, food is available to them both 24 hours a day and they seem to eat non stop, but never put on weight. Why not?
