Awaiting blood results for kidney function. As she's still loosing weight and isn't her usual self. Should get them later today. If her kidneys are failing then I think the kindest thing will be to PTS. In view of her heart I don't want to 'try and manage it' it wouldn't be fair. For the last couple of days she's still interested in things but is not my bossy little diva cat and isn't eating much.
