With temperatures exceeding 30°C in parts of the UK, a cat owner from the Cotswolds has shared a 65p hack using Tesco tuna in spring water to keep feline friends hydrated during the heatwave. The simple trick, posted on Instagram where the owner has over 36,600 followers, involves mixing a can of tuna steaks in spring water with additional water to create a hydrating treat.
How the Tuna Hack Works
The owner, who has two cats named Pearl and Louie, demonstrated the method in a video. She held up a 145g can of Tesco own-brand tuna steaks in spring water, costing 65p, and used a fork to break the tuna chunks into a jug. She then filled the jug halfway with water and mixed it thoroughly. The resulting liquid and small tuna pieces were poured into a water bowl for her cat to drink.
"One can of tuna in spring water, add to a jug of water, and feed in small portions," she wrote in the caption. "Keep it in your fridge covered and let them enjoy throughout the week." Similar products from other brands work as long as the tuna is in spring water, not oil or brine.
Importance of Hydration for Cats
Ensuring cats stay hydrated is crucial during hot weather, as dehydration can lead to potentially fatal kidney problems. According to Cats Protection, one of the most important things owners can do is provide plenty of water and shady spots for outdoor cats. They recommend keeping cats indoors between 10am and 3pm when the sun is at its strongest.
Encouraging regular drinking can be achieved by making water more interesting, such as mixing in tuna, as some cats are notorious for not drinking enough water. Water bowls should be placed away from food and in multiple locations around the home and garden.
Additional Tips for Cat Care in Heatwaves
Cats are generally better at self-regulating in heat than dogs, but owners can still help. Providing multiple water bowls, both indoors and outdoors, and ensuring they have access to cool, shaded areas are key. The tuna hack is an inexpensive way to entice cats to drink more fluids, reducing the risk of heat-related illnesses.
