Sorry for the morbid thread title. My rag doll cat is 18 years old and has recently been diagnosed with chronic renal failure, as is very common in cats of his age so the vet tells me. He's lost a third of his already tiny body weight so we know he hasn't got long. He is not in any discomfort but is very frail. Today when I went down to the kitchen he didn't get up to greet me as normal, just lay in his bed. He's not eaten anything overnight. He came up to the bedroom and got on the bed and has stayed their for the last couple of hours. He does sleep a lot anyway but he just seems different. When I stroke him he doesn't respond, just barely opens his eyes. Does this sound like the end might be near? Not sure whether I should take him to the vet (he's a house cat so this will distress him) or just to leave him be where he is content and quiet (kids aren't here) and if it's his time then let nature take it's course?
