A dull ache sits in my centre. My cat Lucy, immortalised next to my old red keyboard on my Thought Food home page, is gone.
2 days ago the vet in me woke to a 16 year old depressed, immobile, incontinent feline patient. I needed more information before communicating with the cat’s owner, who was also me. The owner could read the vet’s face though and it made her feel as though a cactus was growing in her chest.
The vet came back with information later in the day.
Hypothermia, likely anaemia hiding under haemoconcentration, severe azotemia in the face of likely hyposthenuria, severe hyperglycaemia, and elevated ALT
At that point the owner and the vet in me began to overlap, like a Venn diagram, and both parts of me knew enough to know this:
None of these big words gave us a definitive diagnosis. To get to the big word that was causing the multi organ system problems indicated by a physical exam and first round of blood tests, we’d need to enter a new level of the diagnostics game. And with each new diagnostic test we’d opt for we’d open up the possibility of needing still more tests to get to the bottom of it.
What justifies further diagnostics in veterinary medicine?
The chance that the definitive diagnosis is something treatable or manageable to the point of returning the patient to a good quality of life.
When I started work as a small animal vet in 1998 we had fewer diagnostic and treatment options available for pets. It is good to have more options now. There are absolutely cases where we can return animals to a great quality of life where they would have been euthanased when I first graduated.
But this advanced knowledge also complicates matters, particularly when it comes to caring for our geriatric pets.
People often assume that the hardest part of being a vet is euthanasing animals. Yes, it can be devastating. But I have always found it equally as hard, if not harder, to hand hold people through the process of coming to terms with the fact that it is time to euthanase, while their pet is put through diagnostics and treatments that may prolong life but do nothing for quality of life.
An internal medicine specialist may well have wanted to know exactly what the cause of my cat’s abnormal blood results were before giving me their blessing to euthanase.
And, with those blood test results, had my cat been 2 instead of 16, I still would have stopped to consider that euthanasia could be the end point. But I would have gone ahead with more diagnostics because the chances of them leading to an outcome with a good quality of life for my cat would have been higher.
But I also knew that had I insisted on a definitive diagnosis 2 days ago, Lucy could have spent her last days scared, in a fluorescently lit hospital having rectal temperatures, blood and urine samples taken at regular intervals with no knowledge of why it was happening. Had she been able to come home it would have been heavily medicated, and still not feeling 100%.
When I weighed this with the tiny chance that she was suffering something treatable with a chance of return to good health – the risk of putting her through fear and pain for nothing at the age of 16 was not one I was willing to take.
Instead we made the hard choice.
Instead all four of her people cuddled her. We whispered in her little round ears and wet her fur with our tears. And I stroked her velvet neck as she drifted off into anaesthesia and then away into death.
Later that night I laid down next to Lucy’s siter, Lily and burst into deep sobs. These cats entered my life before the mental illness that came with my human children. With Lucy I have lost another part of me that existed before everything changed irreversibly…and not all for the better. The waves of grief beach unexpected thoughts and feelings.
When I work, I am not brutally honest with a vulnerable client if they ask me ‘What would you do in this situation?’ I stick to the facts, lay out probabilities as best I can and make sure euthanasia is part of the conversation so that they can make their own informed decision, in as much as their own time as their pet’s welfare allows.
But if the vet in me had been advising the cat owner in me for Lucy, I would not have held back. I would have said:
‘We can do every diagnostic test under the sun and you will probably get an answer, but we are doing it for you, not for your pet.’
Just because we can do something, doesn’t always mean we should.
