Blueberries are sweet, bite-sized and packed with antioxidants — but can your curious cat enjoy a blueberry snack alongside you? Whether your feline friend is swatting them off the counter or staring wantingly at your breakfast bowl, it's natural to wonder: can cats eat blueberries? And are blueberries safe for cats?

Let's explore whether blueberries are a safe and healthy treat for your cat to enjoy.

Can Cats Have Blueberries?

The good news: yes, your cat can have blueberries! Knowing which "people foods" are safe for your cat (and which aren't) is a great way to ensure your kitty isn't eating anything they shouldn't. It can also help you offer a variety of different treats, which can keep things exciting for your cat when it comes to training and bonding time. Of course, it's always best to defer to your veterinarian if you're wondering about feeding your cat something new.

So if your furry friend is showing interest when you pull the blueberries out of the refrigerator (and your vet gives the OK), feel free to offer them as a small treat.

Are Blueberries Good for Cats?

Blueberries are a great source of antioxidants and fiber. They are also low in calories, making them a great treat for cats who are overweight. Of course, treats should make up less than 10% of their daily food intake, so make sure to offer them in moderation.

Risks of Feeding Blueberries to Cats

Because blueberries are high in fiber, an excessive amount of blueberries could cause your cat to have an upset tummy. Any time an animal rapidly consumes a large amount of fiber, it can come potentially cause gastrointestinal upset. This can result in loose stool or diarrhea, which is no fun for anybody! So while cats can eat blueberries, it's best not to let them overindulge.

Can Kittens Have Blueberries?

Kittens can have the occasional blueberry, but like adult cats, they shouldn't have an excessive amount. Also, because kittens are growing and have different nutritional requirements than adults, it's best for your kitten to fill up on a complete and balanced kitten food. Kittens require more calories and protein than adult cats. Blueberries are low in calories and protein, so while blueberries are safe for kittens, they need more nutrients than what's available in blueberries to fuel their growth. Let your kitten get their nutrients from their kitten food.

How to Safely Feed Your Cat Blueberries

If you are offering a blueberry to a cat, make sure it's a smaller one. Some blueberries can be quite large, which could make them harder for your cat to eat safely. Also: know your cat! Are they the type to swallow things whole? If so, it might be best to opt for a different treat, since large blueberries could be a choking risk for cats who aren't careful chewers.

You'll also want to stick to fresh blueberries for your cat. Dried and canned blueberries can have added sugar, so it's best not to share those with your cat.

Can Cats Eat Blueberry Extract?

If you find a cat treat that has blueberry extract in the ingredient list, rest assured that it is safe for cats. But keep in mind that since it's an extract, it does not offer the same nutritional benefits that a fresh blueberry would.

"For most adult cats, two or three blueberries a day is fine."

How Many Blueberries Can Cats Eat?

If your cat loves blueberries, they may try to convince you that they can eat the entire container. But when it comes to treats, moderation is key. For most adult cats, two or three blueberries a day is fine.

Treating Your Cat With Care

Knowing what's safe for your cat is a big part of ensuring they stay healthy and happy. Cats may show interest in plenty of people foods that aren't safe for them, so caution on your part as the pet parent is wise. With that said, blueberries are one of those foods that you can give to your cat with your vet's recommendation! So next time you pick up a box from the grocery store, feel free to let your cat indulge.
