How To Fatten Up A Cat?

There are several things you can do to help your feline gain weight over time. Here are some tips you can try:

  • Switch to a high protein food, which is also high in calories. On this list we've reviewed our 5 best picks you can buy online and start feeding them right away.
  • Serve your cat wet food, not only dry. You can switch entirely to wet food or serve half of their meals. You can also add a meal topper. This will give them more variety and should increase their interest in the food.
  • Have a more structured feeding time and schedule. Don't leave the food out for too long. Take it away after 10 or 20 minutes. 
  • Change the feeding schedule. If you've been feeding your feline two large meals during the day, switch to four smaller meals instead, and see if this makes them eat up and finish everything in their bowl.
  • Get an automatic cat feeder. If you find that adjusting their feeding schedule and routine helps them consume more food for the day, you might want to consider getting an automatic cat feeder, which will serve just the right portions even when you are away from home.

Find your cat's favorite flavor and texture

Cats have a preference for the flavor and texture of the food they are eating. Serve your feline different flavors until you find their favorite one: chicken, duck, salmon, beef, etc.

The texture is also important, with wet food you'll be able to find smooth pate, minced, to meat-cubes. 

Also, some cat might prefer cooked food other than a pre-made one so if you want to help it gain weight, you should cook the food yourself. It’s very simple, some meat and veggies are fine.

Is it good to keep feeding my cat pre-made food?

Now, I’ve heard this question many times. It’s not always bad to feed yours with pre-made food because it’s often made with all the necessary nutrition that your cat needs.

But if being fed for a long time, the preservative might affect its health. Overall, make sure you've picked a brand that manufactures nutritional and healthy food.

Should I choose dry food or wet food? 

It depends on how you’re going to use it. Dry food can be kept for a long time compared to wet ones. But the nutrition in it is often reduced in this state. On the other hand, wet food has a high amount of nutrition in comparison to dry one but they’re harder to preserve.

Bottom line

If your lovely feline is not gaining enough weight, the first thing you can do is switch to a more protein rich and high calorie food. Our number one recommendation is the Blue Buffalo Wilderness Chicken Recipe, which is high in protein and has healthy carbohydrates inside such as sweet potatoes and peas. It also contains, fatty acids, vitamins and antioxidants. For more flavor choices, make sure you check all the products on this list.
