Feeding your feline friend might seem straightforward, but there are several pitfalls that can impact their health and well-being. As cat lovers, we want the best for our furry companions, and ensuring they have a proper diet is crucial. Cats are unique creatures with specific dietary needs that differ greatly from other pets. Understanding what not to do when feeding your cat can make all the difference in their overall health. Let’s explore these common feeding mistakes and ensure our cats thrive.
Don’t Feed Your Cat Dog Food
It might be tempting to think that all pet food is created equal, but cat and dog food are distinctly different. Cats are obligate carnivores, which means they require a diet primarily composed of meat. Dog food lacks the essential nutrients that cats need, such as taurine, an amino acid vital for a cat’s heart and vision health. Feeding your cat dog food can lead to nutritional deficiencies and long-term health issues. Always ensure you’re providing food specifically formulated for cats to meet their unique dietary needs.
Avoid Feeding Your Cat Raw Fish
While it might seem natural to feed your cat fish, especially if they seem to crave it, raw fish can pose significant health risks. Raw fish contains an enzyme called thiaminase, which destroys thiamine, an essential B vitamin. A deficiency in thiamine can lead to neurological problems and severe health issues. Additionally, raw fish may contain harmful bacteria or parasites. Cooked fish is a safer alternative, but it should still be given in moderation to avoid an imbalance in their diet.
Refrain from Giving Your Cat Milk
The image of a cat lapping up a bowl of milk is a common stereotype, but in reality, most cats are lactose intolerant. Milk can cause digestive upset, including diarrhea and stomach cramps. While some cats may tolerate small amounts, it’s generally best to avoid it altogether. Instead, provide fresh water as their primary liquid intake. If your cat loves milk, there are lactose-free options available specifically for cats, but these should also be given sparingly.
Don’t Let Your Cat Eat Too Much Tuna
Tuna is another food that cats seem to love, but it shouldn’t become a staple in their diet. While it’s fine as an occasional treat, too much tuna can lead to mercury poisoning and nutritional imbalances. Tuna lacks the essential nutrients that a complete cat food provides. If your cat is a tuna fanatic, consider tuna-flavored cat food that is balanced for their dietary needs. Always remember, moderation is key.
Avoid Overfeeding Your Cat
Overfeeding is a common mistake among cat owners, often leading to obesity, which can cause a plethora of health problems, including diabetes and joint issues. Cats are not great at regulating their food intake, so it’s up to us to monitor their portion sizes. Follow the feeding guidelines on cat food packaging and consult your vet for personalized advice. Regularly weigh your cat to ensure they’re maintaining a healthy weight.
Never Feed Your Cat Bones
Bones, especially cooked ones, can be dangerous for cats. They can splinter and cause injuries to the mouth, throat, or intestines. Even raw bones, while less likely to splinter, can still pose a choking hazard or cause dental fractures. It’s safer to provide dental treats designed for cats, which help maintain oral health without the risks associated with bones.
Avoid Feeding Your Cat Table Scraps
While it might be hard to resist those pleading eyes, feeding your cat table scraps can lead to an unbalanced diet and potential toxicity. Many human foods, such as onions, garlic, and chocolate, are toxic to cats. Additionally, table scraps can contribute to obesity and digestive upset. It’s best to stick to specially formulated cat treats and food to ensure your cat gets the nutrients they need.
Don’t Ignore Food Allergies or Sensitivities
Just like humans, cats can have food allergies or sensitivities. Common signs include itching, vomiting, diarrhea, and skin irritations. If you suspect your cat has a food allergy, consult your vet to identify the culprit and find suitable alternatives. Ignoring these signs can lead to chronic health issues and discomfort for your cat. A proper diagnosis and dietary adjustments can significantly improve their quality of life.
Never Leave Food Out All Day
While free-feeding might seem convenient, it can lead to overeating and obesity. Leaving food out all day also increases the risk of spoilage, particularly with wet food. Instead, establish a feeding schedule with set meal times. This not only helps control your cat’s weight but also creates a routine that your cat will appreciate. If your cat prefers grazing, consider using a puzzle feeder to make meal times more engaging and controlled.
Avoid Feeding Your Cat a Vegetarian or Vegan Diet
Cats are obligate carnivores, meaning they require meat to thrive. A vegetarian or vegan diet lacks essential nutrients that are naturally found in animal products. Taurine, arachidonic acid, vitamin A, and vitamin B12 are crucial for a cat’s health and are not adequately supplied by plant-based foods. Attempting to feed your cat a vegetarian or vegan diet can lead to severe nutritional deficiencies and health problems.
Don’t Rely Solely on Dry Food
While dry food is convenient and helps with dental health, it shouldn’t be the sole component of your cat’s diet. Cats naturally have a low thirst drive and may not drink enough water, leading to dehydration. Incorporating wet food into their diet helps increase their moisture intake, supporting urinary tract health. A balanced diet that includes both wet and dry food can provide the necessary nutrients and hydration your cat needs.
Never Skip Veterinary Dietary Advice
When it comes to your cat’s diet, your veterinarian is your best resource. They can provide tailored advice based on your cat’s age, weight, health, and lifestyle. Ignoring professional dietary advice can lead to unintended health consequences. Regular check-ups and open communication with your vet ensure that your cat’s dietary needs are met, contributing to a long and healthy life.
By being mindful of these common feeding mistakes, you can ensure your cat stays healthy and happy. Remember, a well-fed cat is a content cat, and taking the time to understand their dietary needs is one of the best ways to show your love.

Linnea is a born and bred Swede but spends as much time as possible in Cape Town, South Africa. This is mainly due to Cape Town’s extraordinary scenery, wildlife, and atmosphere (in other words, because Cape Town is heaven on earth.) That being said, Sweden’s majestic forests forever hold a special place in her heart. Linnea spends as much time as she can close to the ocean collecting sea shells or in the park admiring puppies.
