My cat is a 16 year old burmese house cat. He's always been fit and healthy up till the last year when he developed arthritis. He's currently on a monthly injection for this which is meant to be done every 4 weeks but it stopped being effective at the end of the 3rd week so now he has it every 3 weeks. We can definitely tell when it's wearing off, he walks very stiffly, reluctant to jump onto things, sometimes has visible signs of pain. He spends most of his time sleeping but a couple of times a day he gets up for a wander and to mug us for pieces of ham.
We had blood tests done a month ago as he had lost weight despite an increased appetite (eating his own and the dogs food) and the vet was slightly concerned about his kidneys, but said get him tested again in a month or two to see if he's deteriorated. We are now 3 weeks since his last injection and i think it's worn off just before the three week mark. He's also spotting urine which suggests a UTI as he's had them regularly throughout his life.
So he's still got some quality of life, he's able to get around, enjoys his favourite food and interacts with us. But his injection is wearing off quicker, and it's only masking the pain. Sometimes i look at him and think he really doesn't look well (but then he's an old longhaired cat, so while he still grooms he's not as good at it as he was.)
He won't take oral meds at all and it's traumatic for him to be forced to take them which is why he's on this monthly injection as opposed to metacam. I've spoken to the vet and if there is any kidney issues, the medication that would be oral and it would be really really stressful for him to have that given every day - if he would even take it.
Cost isn't an issue, but I'm struggling with whether it's right to say goodbye to him now while he's still happy-ish and while the injections are still working, or to keep him going for a few months more. I think he's only going to deteriorate and I'm not sure where the line is. I am so conscious of leaving him too long and turning round one day and suddenly seeing I've let him get too bad. I've seen it happen with members of my family and i don't want to do it to my boy.
I don't know how i feel about waiting for "something" to happen to force my hand, or for him to get full blown kidney failure before i decide it's time. He may have a few more months left going along as he is but if I've waited till he's in a lot of pain, surely I've left it too long?
What would you do?
