Hi, as cat owners can we request our cat to be PTS? Mine is nearly 19, she's slowed down a lot, not grooming much so coat is getting matted despite me brushing as best i can, can still jump but not as easily so i suspect aching joints. I don't want to go the vet to be told we can do this test and that etc, she's an old lady and i want her to go before she's too uncomfortable, but don't want to seem like heartless cow to a vet for refusing any tests/medication etc.
