Recognizing when a Turkish Van is approaching the end of life is one of the most difficult responsibilities of pet ownership, made more challenging by the feline instinct to conceal pain and vulnerability. Cats evolved as both predators and prey, and showing weakness is deeply contrary to their nature. This means that by the time signs of decline become obvious to even an attentive owner, the cat may have been struggling for some time.
The signs of terminal decline often develop gradually. Progressive weight loss despite adequate food availability is one of the earliest and most consistent indicators. Muscle wasting becomes apparent along the spine and hindquarters, and the cat may feel bony when you stroke its back. Appetite typically decreases, sometimes dramatically, and the cat may approach its food bowl with apparent interest but then walk away without eating, or eat only a few bites before stopping.
Withdrawal from social interaction is another significant sign in a breed as people-oriented as the Turkish Van. A cat that has always been at the center of household activity and now seeks out hiding places, avoids contact, or no longer comes to greet you is communicating something important. Changes in grooming behavior are also telling. A cat that stops grooming itself, resulting in a dull, unkempt coat, has often lost the energy or the physical comfort needed to maintain this basic self-care behavior.
Other signs to watch for include labored or open-mouth breathing, persistent vomiting or diarrhea that does not respond to treatment, incontinence, disorientation or confusion beyond what might be attributed to cognitive decline, and a general sense that the cat is no longer engaged with or interested in the world around it. Trust your knowledge of your individual cat. You know their normal better than anyone, and your perception that something has fundamentally changed is valid and important.
