My cat JB is almost 18 and showing lots of signs that he's declining cognitively. My little shadow who has always thought I'm his mum (hand reared orphaned kitten) sometimes doesn't seem to know me or enjoy the things he always did before. He doesn't go outside anymore and if we take him out he doesn't seem to know where he is or what to do. He pees in all sorts of places. He zooms around and vocalises like he's been terrified. He jerks his head all the time like he's got something neurological going on. He doesn't often respond to his name anymore when it still had him running to me this time last year. He forgets he's been fed. He doesn't groom himself very often and he's lost loads of weight but the vet says they won't test him for disorders or illnesses as he gets too distressed for bloods and needs sedating, which is dangerous at his age. She says he's just a very old boy but "the time will come to say goodbye"
How will I know if it's "time"? My heart will shatter in my chest, because he's been with me all his life and half of mine, but I owe him a dignified and peaceful end if I can provide it for him. How will I know?
