Is it OK to feed a cat canned tuna?

There is a chance that you have heard rumors about tuna. Some say it’s great, others say it’s not good for cats, so which is it?

Cats can eat tuna but in moderation. You will find most cats will love the taste, but it’s still not an ideal replacement for a well-balanced diet. This is because it does not contain sufficient nutrients for your cat on its own. Also, too much tuna can cause mercury poisoning.

You have learned that cats can have tuna, but not too much. Keep reading to see what you can do to get your cat’s appetite back.

How can I get my cat’s appetite back?

If your cat is off its food and you are concerned you may be looking for some ways to get his appetite back. There are three things you can try:

  • Strong smelling wet food.
  • Baby food laced with tuna juice
  • Low sodium chicken broth

Strong smelling wet food

Cats have a strong sense of smell. You can use this to your advantage by offering them some strong-smelling food to arouse their appetite.

Baby food laced with tuna juice

Earlier I mentioned that cats like the taste of tuna, remember? Well, you can use this to your advantage. Get some meat-based baby food and lace it with some tuna juice from a can. Hopefully, she will lap it up and get her appetite back.

Low sodium chicken broth

Another trick is adding chicken broth to your cat’s food. But, make sure it’s low-sodium chicken broth. And, do not put too much in there, just enough to arouse her interest.

Do Cats Get Bored Of The Same Food?

Cats can start to get bored of eating the same food each day, especially if it lacks flavor or the right nutrients. Trying to break up the type of food you give them throughout the day can be of benefit. For example, let them have dry kibble most of the day, and give them some wet food either at breakfast or dinner.

Since cats tend to love wet food more, you can opt to give them a higher percentage of wet to dry food. Just be sure you’re watching the calories and nutritional benefits of the food, as wet food is often higher in calories and lower in much-needed nutrition.

How Long Can You Leave Wet Cat Food In The Fridge?

You should not leave wet cat food in the fridge for longer than one week. It will start to diminish in quality, taste, and scent, and your cat is likely to turn its nose up at it if it’s been in the fridge for any longer.

As wet food sits in the fridge, the scent and flavor start to diminish over time. This is despite how tightly sealed your container of choice is. As such, over time, the food becomes less appealing to your feline friend.

Why Do Cats Suddenly Not Like Their Food?

If you purchase very large bags, it could be that their kibble is going stale before your cat has the chance to work through the bag. When it comes to kibble, quality can start to diminish as soon as your bag is opened.

With wet food, your cat might still like the food you’ve presented, but they might not want to eat it if it’s too cold. Cats aren’t fans of cold food, so you want to ensure you warm up the wet food if it’s been in the fridge or has been sitting in their dish for a while.

You should also be sure you’re feeding your cat out of a clean dish. Don’t reuse dishes often before washing them, as your cat won’t want to eat out of a dirty dish.

How Do You Throw Away Cat Food?

One way to dispose of cat food is to pour it into a ziplock bag that is stored in the fridge or freezer. Once the bag is full, you can throw it away in the regular garbage. You can just scrape the excess wet food into the garbage, but the smell is so pungent that it’ll radiate through the area until you get rid of the garbage.

Can I Flush Wet Cat Food Down The Toilet?

Cat food, or any food, should never be flushed down the toilet. Our waste systems are not meant to handle undigested food, and you could end up with a clogged toilet or backed-up sewage system.
