When your cat gives you those irresistible eyes while you’re enjoying a Subway tuna sub, it’s hard not to share. But is it safe for cats to eat Subway tuna subs? While tuna might seem like a natural choice for your feline friend, the added ingredients in a Subway sub—like mayonnaise, bread, and seasonings—can be a different story. Let’s dive into whether this snack is safe, what to watch for, and how to keep your cat healthy.
🐟 Can Cats Eat Tuna?
Cats are natural fish lovers, and tuna is often their favorite. Tuna is packed with protein and omega-3 fatty acids that can be beneficial for their skin, coat, and overall health. However, not all tuna is created equal, and too much of it can cause problems.
Fresh, cooked tuna without seasonings or oils is generally safe for cats in small amounts. But canned tuna, especially the type used in Subway’s tuna sub, often contains added salt, oils, and preservatives that aren’t ideal for your cat. Regularly feeding tuna to cats can also lead to mercury poisoning or nutritional imbalances since tuna lacks essential nutrients like taurine that cats need to thrive.
🥪 What’s in a Subway Tuna Sub?
A Subway tuna sub is more than just fish. Its ingredients include mayonnaise, seasonings, bread, and often optional toppings like onions, lettuce, and cheese. While these may be delicious for humans, they can pose risks to your cat. Let’s break it down:
- Tuna: The tuna itself may contain added salt or oils, which aren’t ideal for cats. Additionally, the tuna used by Subway is typically mixed with mayonnaise.
- Mayonnaise: Mayo is high in fat and calories, which can upset your cat’s stomach or contribute to obesity if consumed in large amounts.
- Bread: Bread isn’t toxic to cats, but it has no nutritional value for them. It can also be hard for some cats to digest.
- Seasonings: Subway’s tuna often contains salt, which is harmful to cats in excess. Onion or garlic powder, if present, can be toxic to cats even in small quantities.
- Toppings: Ingredients like onions and garlic are toxic to cats, while lettuce and cheese may cause digestive upset depending on your cat’s tolerance.
Given all these factors, it’s clear that the Subway tuna sub isn’t a cat-friendly meal.
🍴 What Happens if Cats Eat Subway Tuna Sub?
If your cat sneaks a bite of your Subway tuna sub, it’s unlikely to cause immediate harm in small amounts. However, there are some potential risks to keep in mind:
- Digestive upset: Ingredients like mayonnaise and bread can upset your cat’s stomach, leading to diarrhea or vomiting.
- Sodium toxicity: The added salt in the tuna or seasonings can cause symptoms like lethargy, excessive thirst, and even seizures in severe cases.
- Allergic reactions: Some cats may have food sensitivities to dairy or other ingredients in the sub, causing skin irritation or digestive issues.
- Toxicity: If the sub contains onions, garlic, or similar ingredients, it could lead to anemia and other serious health problems.
If your cat eats a significant portion of a Subway tuna sub and shows symptoms like vomiting, diarrhea, lethargy, or difficulty breathing, contact your vet immediately.
🐾 Safer Alternatives for Cats
Instead of sharing your Subway tuna sub, consider offering your cat a safer treat. Here are some feline-friendly options:
- Plain, cooked tuna without salt, oil, or seasonings
- Canned tuna in water (as an occasional treat)
- Cooked salmon or whitefish
- Commercial cat treats made with fish
- High-quality wet cat food with fish as the main ingredient
These options provide the taste of fish that cats love without the risks associated with human foods.
🩺 When to Call a Vet
If your cat eats a small piece of Subway tuna sub without harmful toppings, they’ll likely be fine. However, you should contact your vet if you notice any of the following symptoms:
- Repeated vomiting or diarrhea
- Lethargy or weakness
- Excessive thirst or urination
- Pale gums or difficulty breathing
- Loss of appetite or sudden weight changes
Early intervention can prevent more serious health issues, so don’t hesitate to seek veterinary advice if you’re concerned.
