What you need to know about liquid diets for cats

While most cats will do just fine with regular cat food throughout their lives, sometimes cats need a little extra TLC. If your cat is recovering from an illness or surgery, she might not be all that excited about eating her food. In some situations, your vet might prescribe a liquid diet for your cat. You’ll need to give your cat some extra care, but with liquid cat food, you can get that important nutrition into your cat, even if she’s not feeling hungry. Whether your vet has just recommended a liquid diet or you want to research them just in case, knowing the details of feeding your cat liquid food can help you be prepared if your cat ever needs this specialized care.

When to feed a liquid diet

Your vet might recommend that you feed liquid cat food in several different instances:

  • Orphaned kittens might need to be fed liquid milk replacer.
  • More commonly, a cat who’s recovering from surgery or an illness might lose their appetite and need a liquid diet for a few days as they regain their strength.
  • Some older cats who are unwell or in pain might also benefit from a liquid diet.

In most cases, a liquid diet for cats isn’t a long-term solution and is instead intended to get a cat through a rough period so they can regain their strength and return to their typical diets. However, cats who have cancer or kidney disease might benefit from a long-term liquid diet. Liquid diets should only be fed under your vet’s supervision and instruction since a cat who is unwell enough to require a liquid diet will probably require other treatments and careful monitoring.

Potential liquid diets for cats

There are many commercially available liquid diets for cats, and they’re formulated to ensure your cat gets the nutrition she needs. If you’re looking for a milk replacer for kittens, Whiskas Catmilk for Cats and Kittens is easy to digest and comes already formulated as a liquid.

Most liquid diets intended for adult cats require a prescription, and your vet will surely recommend the one they think is best for your cat.

You may also be able to create your own liquid diet for your cat. You can puree traditional wet cat food in a blender and add some water to create more of a broth. This is ideal because you retain the balanced nutrition that already exists in the cat food. Alternatively, your vet might recommend using low-sodium chicken broth as a short-term solution. If you’re considering making your own liquid diet, be sure to consult with your vet to verify that it will meet your cat’s nutritional requirements.

How to feed a liquid diet

In most cases, you may need to syringe-feed your cat a liquid diet, especially as she is just starting to recover. Your vet will provide you with a syringe and detailed instructions on how much to feed your cat and when. Syringe feeding will take time, and it’s a temporary solution that you might need to perform over a few days. You’ll also want to provide your cat with free access to water.

As your cat regains her strength, she may start to feel strong enough to eat on her own. Warming up her liquid food can make it more tempting, encouraging her to eat. A few seconds in the microwave will usually do the trick, but be sure to stir the food thoroughly and carefully check its temperature before giving it to your cat.

Feeding a liquid diet requires some extra time and patience, but it’s often a necessary aspect of caring for your cat when she’s unwell. If you ever have questions about the diet or your cat’s health, talk to your vet right away. A cat who doesn’t eat can quickly become dehydrated and lose strength, so it’s important to get your cat the care she needs. By choosing the right liquid diet and following your vet’s instructions, you may be able to give your cat all the care she needs right at home. However, in some cases, cats may need to return to the vet for IV treatments and other supportive care to get them through a tough health period.

Do cats understand kisses? What science says
Your cat may or may not take to this human behavior
Woman kissing her cat

Why do we give our pets kisses? For us, it shows affection and devotion to our animals, including by reinforcing the physical bond between us. But when we give our felines a peck on the head and they glare up at us, it's easy to wonder what they feel during this sign of our love.

Do cats understand kisses? To get to the heart of this question, we first have to think about how our kitties feel about us. Scientists don't have a consensus on whether cats feel love (in the same way we do) for us and how we should interpret their behavior. It seems that some mousers do indeed enjoy getting a kiss or two, while others certainly probably don't enjoy it.

Health concerns to harmless changes: Reasons cats stick out their tongues
Side view of a cat sticking out its tongue

If you've ever wondered, "Why do cats stick out their tongues?" you're not alone. Whether you've noticed your cat doing it and wondered whether your cat is sick, or you've simply seen a cute TikTok, try not to worry. Most cats occasionally "blep" or stick their tongues out, and it's rarely a cause for concern. In fact, it's downright adorable! (Search for 'cat bleps' online when you're feeling down; the precious images are the perfect pick-me-up.)
What causes cats to blep? We'll explore a few potential reasons behind this strange yet adorable behavior.
Why do cats stick out their tongues? Here are a few reasons

As odd as this behavior may look, you'll be glad to know that you rarely need to worry about a cat sticking out their tongue.
Your cat is exploring the world with their tongue
One of the most common reasons for an exposed tongue is rather simple: your cat is literally exploring their surroundings. When your cat leaves their mouth open and tongue out, they're collecting pheromones on their tongue -- this is called the Flehmen response. Those pheromones give your cat important information about other cats around, including whether they're in heat, via electrical signals from body to brain. Who knew something so cute could be so helpful, too?
Your cat may show their tongue if they're missing teeth
Sometimes, cats let their tongue hang out a little because they're missing their canine or front teeth. These teeth help keep the tongue within the mouth, so if your cat is missing one or two of these teeth, it's more likely that their tongue will slip out from time to time. No worries!
Your cat is trying to please you with a behavior they think you like
You might even be reinforcing your cat to stick their tongue out without knowing! If you laugh at your cat, give them attention, or give them a treat when they do this behavior, they may quickly learn that sticking out their tongue gets a positive response. You might start to see your cat do this repeatedly, mainly to get a positive reaction from you. Whether that's 'good' or not is up to you to decide.
Your cat may let their tongue fall out of their mouth when they're relaxed
Sometimes, when cats are relaxed, their tongues naturally slip out. This happens because your cat's jaw loosens up as they relax, so their mouth opens up just enough to let the tongue through.

A Cornish Rex lies on a bed

Those of us with curly-haired cats adore their wavy locks. They're fun to pet, and they look cute as can be, too. However, this strange gene only occurs in a few breeds, meaning they're rare, and acquiring one can be difficult and expensive. Many cats with curly hair fall under the "rex" designation and can set you back upward of $1,000 or even more. If your heart is set on a pet with little ringlets, you'll likely bring home one of these precious breeds.
What to know before getting a cat with curly hair?

You should never bring home an animal based on appearance, but we can't deny that their kinked hair gives cats with curly fur a distinct look. One interesting thing to note is that many of these kitties shed less and don't require substantial grooming — certainly a bonus for a pet owner.
