The Tuna-Water Trick for a Cat Who Stopped Drinking

Time:2026-08-28   Number of visits:1004

Bramble stopped drinking and I noticed because the water bowl, which I top up every morning out of habit, had not dropped a measurable inch in two days. Cats are quiet about trouble, which is why they end up at the vet in a worse state than dogs, and a cat who isn't drinking is a cat heading somewhere I didn't want to pay to visit. So I did what every worried owner does and called the surgery before I'd finished my first coffee, bracing for the bill.

The nurse asked the question that tells you everything: is she eating? She was. Was she peeing? Yes, normally. Then the advice was gentle and cheap, the kind you feel faintly silly for not having tried. Offer her something she can't resist. For a cat, that is often the liquid from a tin of tuna, the brine she'd lick off the lid given half a chance, diluted a little so it isn't a salt bomb, and presented in a shallow dish she can't whiskers-bump.

I opened a tin, tipped the water into a cup, added an equal splash of fresh water to take the edge off, and put it down. She drank. Not a lot, not dramatically, but the act of drinking, which she had declined for two days, happened in front of me, and I felt my shoulders come down from around my ears. Cats are drawn to that fishy smell the way we're drawn to fresh bread, and a reluctant drinker will often take tuna-water when plain water reads as nothing at all.

The why of it is simple once someone says it out loud. Cats evolved in places where they got most of their moisture from prey, and a house cat on dry food is quietly under-watered even when everything looks fine. Bramble had just tipped from quietly under-watered to noticeably not-drinking, and the tuna water was a bridge back to the habit, not a meal replacement and not a long-term plan. Within a day she was back at her normal bowl, and the crisis, such as it was, had cost me a tin of tuna and a small fright.

I did learn the lesson underneath it, though. The bowl itself might have been the problem. Cats hate a deep bowl that presses their whiskers, and they dislike still water that's been sitting, and a bowl near the food smells like the food and puts them off. I moved hers to a wide, shallow dish, away from the biscuits, and I started running the tap for a few seconds each morning so there's a bit of movement. She likes the moving water, the way most cats do, and the simple change keeps her interested.

None of this replaces a real problem. If a cat won't drink for more than a day, or stops eating too, or seems off in herself, the tuna water is not the answer, it's the thing you try while you phone the vet. Dehydration in a cat turns serious faster than owners expect, because their systems are small and their reserves are smaller. I keep that number saved, because the one time I needed it, I needed it fast and fumbling for it was the last thing I wanted.

I've since bought a little fountain, the kind with a quiet pump that keeps the water moving, and she took to it the way she took to the tuna water, which is to say immediately and without the suspicion she reserves for new furniture. The fountain is the long-term fix; the tuna water was the emergency. Between them they've turned a two-day scare into a routine I barely think about, which is the best kind of outcome with a cat.

Bramble is fine now, back to ignoring me from across the kitchen, and the tuna tin has become a tool in the cupboard rather than a treat I feel guilty about. A spoon of the water, now and then, when she's being difficult about the bowl. It's the cheapest insurance I've ever bought, it tastes to her like the best thing in the world, and it bought me a calm evening I'd have spent at the emergency desk instead.

I keep a tin in the cupboard now as a deliberate tool rather than a happy accident, the way some people keep a thermometer and a number for the surgery. It's not an everyday feed, just the thing I reach for when a cat goes quiet at the bowl, a cheap first move before the worry turns into a bill I didn't budget for. The fountain does the daily work; the tuna water is the emergency that buys a calm evening, and between them I've stopped fearing the sight of an untouched water dish when I come down in the morning.

The lesson travels beyond cats. Most pets hide thirst and most owners notice too late, and the fix is usually smaller than the fear that grows around it. A scent they can't resist, a bowl shaped right, a bit of movement in still water, these are the unglamorous answers that keep a small animal hydrated through a hot week. Bramble taught me to look at the bowl first and the bill last, and that order has saved me more than money, it's saved me a night of staring at a cat who wouldn't drink.
