If you’re considering changing your cat’s diet and want to know how to switch cat food, then you’re in the right place.

Many cats become accustomed to a particular diet and it can be tricky to transition them to a new one. It’s important to make sure that the switch is done correctly and safely.

In this article, we’ll provide a step-by-step guide to safely changing your cat’s food so that you can transition your cat to a new diet without any health risks, or having to clean up cat vomit and diarrhea.

Step1: Why are You Changing Cat Food?

Consider first why you are changing cat food and if it is necessary. There are lots of reasons why pet owners decide to change their cat’s food, such as:

  • Medically advised: Some cats, for example with kidney issues, are often recommended to eat a different, simpler diet. Changing from regular cat food to chicken breast might sound nicer to us but it might not be so easy for your cat.  One of my cats got a urinary infection and we had to change his diet. 
  • More control: Many owners want to make homemade cat food or feed their cats a raw diet so they know exactly what’s going into their cat’s diet.
  • Different brands: Some cats suddenly go off a brand for no reason at all and demand another. 
  • Age-specific food: You may want to transition your kitten onto adult cat food, or your older cat onto senior food. 

It’s best to check with your vet before you change your cat’s diet. They can advise on any health issues and answer any questions you might have. For whatever reason you are changing cat food, you should make sure that your cat’s food will meet their nutritional needs before you make a switch.

You should also consider the type of food you’re switching to.

  • Is it wet or dry food, or a combination of both?
  • Is it a natural or organic food, or a raw food diet?
  • Is it a grain-free food?
  • Is it high in protein and nutritionally complete?

All of these factors can have an impact on your cat’s health, so it’s important to do your research and make sure you’re choosing the right food for your cat. It is also important to remember that cats are obligate carnivores, so their diet should include plenty of animal-based proteins.

The Process of Transitioning Your Cat to a New Food

Now that you’ve done your research and you’ve chosen the right food for your cat, it’s time to start the process of transitioning your cat to the new food.

The most important thing when thinking about how to transition your cat’s food is to take it slow. You don’t want to suddenly feed them something else as this could cause vomiting, diarrhea or stomach pain.

The process should be done gradually over the course of 10 days to ensure that your cat’s digestive system has time to adjust. Taking ten days to transition to new food, introduces the food in such gradual amounts that your cat will hardly notice.

It’s also important that you keep to their normal feeding schedule and feed them in the same place. You don’t want to change too many things at once as it could unnerve them. 

Here is the step by step guide:

Step 2: How to Switch Cat Food Safely (and Avoid Cat Diarrhea)

Day 1 to 3: Try mixing roughly 25% of the new food in with their old. Hopefully, they’ll be intrigued by the new flavor or texture but there’ll be enough of what they’re used to for them not to mind. 

Day 4 to 6: Once they’re happy eating 25% of the new mixed-in food, up it to 50%. 

Day 7 to 9: Give them 25% of the old food and 75% of the new. 

Day 10: 100% new food. 

You might notice that your cat is quite happy to gobble up the new food. If this is the case, you can up the percentages of the new cat food a little earlier. If you have a very picky cat, it may take them even longer than 10 days to get used to their change in diet, so be prepared to extend the transition period to 2-3 weeks.

It’s also important to monitor your cat’s reaction to the new food. Watch for signs of digestive upset such as vomiting, diarrhea, or decreased appetite. If you notice any of these signs, you should stop the transition process and consult your veterinarian.

Tips for Making the Transition Easier

There are some simple tips you can follow to make the transition process easier for both you and your cat. First, try to make the transition process as gradual as possible. According to the PSDA, cats need at least 10 days to switch to new cat food, some cats even longer if they are fussy.

Don’t try to switch your cat’s food too quickly. This can cause digestive upset and may cause your cat to become picky about their food.

It’s also important to make sure your cat is getting plenty of water during the transition. This will help keep them stay hydrated and will make it easier for them to digest the new food.

What to Do if Your Cat Refuses to Eat the New Food

If your cat refuses to eat the new food, don’t panic. There are a few things you can do to encourage them to eat. First, try adding a small amount of wet food or a high-quality treat to the new food to make it more appealing. You can also try warming the food, as some cats prefer their food at a slightly warmer temperature.

If your cat still refuses to eat the new food, you may want to try switching back to the old food for a few days to give them time to adjust. Then, you can slowly start transitioning them back to the new food.

How to Switch From Dry to Wet Food

If you’re transitioning your cat from dry to wet food, follow the ten day plan above and increase the amount of wet food in their diet gradually. Start by offering a small amount of wet food in addition to their usual dry food. Make sure to monitor your cat’s reaction to the wet food. If they seem to like it, you can gradually increase the amount of wet food you offer.

It’s also important to make sure that your cat is getting enough water. Offer your cat fresh, clean water throughout the day and make sure they have access to it at all times.

How to Switch From Wet to Dry Food

If you’re transitioning your cat from wet to dry food, the same rule applies. Follow the ten day transition guide above, starting with 25% of dry food mixed in with the wet food. Gradually increase the amount of dry food and decrease the amount of wet food until your cat is eating all dry food.

It’s important to make sure that your cat is getting enough water. Cat’s that eat a dry food diet only don’t absorb as much moisture from the kibble as they would from wet food. Offer your cat clean, fresh water throughout the day and make sure they have access to water at all times.

What to Do if Your Cat Has an Adverse Reaction to the New Food

If your cat has an adverse reaction to the new food, you should stop the transition process. Go back to the original food until your cat is settled and well. If you are concerned for the health of your cat, always consult a veterinarian.

It’s important to remember that cats are obligate carnivores, so their diet should include plenty of animal-based proteins.
