Why Is Being Overweight a Problem for Your Cat? 

best cat food for weight loss

Obesity and being overweight can cause massive health problems and, ultimately, shorten your cat’s life expectancy. Even if it’s just a little extra weight, the more they weigh the less likely they are to exercise and so it goes on… 

Overweight cats can develop diabetes, cancers (especially intra-abdominal), painful osteoarthritis, and urinary and bladder issues. The longer you leave it, the harder it will be for them to shed the pounds, so it’s worth noticing it early on, feeding them healthy cat food for overweight cats and encouraging them to play and move more. 

Being overweight can also affect your cat’s mood. Heavier cats tend to be more lethargic, less playful, and less engaged with their family members. If your cat is a healthy weight, they’ll be more likely to engage in their surroundings and play with you!

Causes of Obesity in Cats 

When it comes to weight gain, cats aren’t all that dissimilar to humans. There are many factors at play – it’s not (always) just a case of you giving them one too many yummy treats. If you suspect your cat is suffering from an underlying health condition that’s causing them to put on the pounds, it’s important to take them to the vet for a checkup. 

Some of the most common causes of weight gain in cats are: 

  • Overfeeding and not enough exercise 
  • Genetics 
  • Breed – breeds such as Sphinx, Persian and Ragamuffin are more likely to put on weight 
  • Hypothyroidism 
  • Stress
  • Medication 
  • Spaying or neutering 
  • Pain (if they have an injury that stops them moving) 

Why are indoor cats more prone to being overweight?

Unlike outdoor cats, indoor kitties don’t have huge areas to roam and play in. They can’t use up energy chasing and hunting (unless your indoor cat is anything like mine and manages to catch birds from the balcony)! They generally spend more time lounging around on the couch and being less active.  

As an owner, it’s really important you buy them the best cat food for indoor cats which is specifically formulated to keep indoor kitties a healthy weight and prevent them from becoming obese. 

How can you help your cat lose weight?

The first thing to note is that drastically changing your cat’s diet from one day to the next isn’t going to help them. Massively restricting their calorie intake quickly can actually do more harm and cause them to suffer from conditions such as fatty liver syndrome. Cats aren’t built the same as humans and they can’t store as much energy as us. They need a regular supply of protein for their organs to fully function.  

Before slowly reducing your cat’s calorie intake, it’s important to speak with your vet. They can advise on the best way to do it and also rule out any underlying medical conditions which could potentially be causing your cat to put on weight.  

It’s also important to consider what, how often, and how much you feed your cat. Getting any of the best cat food for overweight indoor cats on this list will help you to monitor their calorie intake and aid weight loss. It’s also worth strictly following the feeding guidelines so you’re not tempted to give them a little extra! 

And it’s not all about food. Getting your cat moving can really help them to lose some weight. There are plenty of ways you can encourage your indoor cat to play and have fun – catios, puzzle toys, and climbing frames are a great way for them to explore their environment and burn up some energy! 

What to Look for When Buying Food for Overweight Indoor Cats

It can feel really overwhelming when you’re faced with all the multiple options of cat food to buy. We’ve broken down the important bits so you know what should and shouldn’t be included in your cat’s meal! 

Wet vs Dry Cat Food? 

Whether you should buy your cat wet food or dry kibble really depends on what they prefer and the calorie content in any particular brand. Cats in the wild like to eat many different types of meat that have different textures – so in all likelihood, your cat will too!  

Cats usually get a high percentage of their liquid intake from their food, so if you don’t have a big drinker, feeding them wet food can be really helpful. 

Generally speaking – although it really does depend on the brand – wet food has fewer calories and a lower fat content than kibble. It has more liquid in it than dry cat food which can help to make your cat feel full. It is, however, easier to overfeed your pet with wet food, so it’s really important you measure it out well. 

To get the best of both worlds, you may want to add some extra water to your cat’s kibble. This allows you to accurately weigh out the food but they also get the added benefits of more water. 

Protein 

Protein is a really important part of your cat’s diet. Not only does it help them stay fuller for longer (so less begging throughout the day), it also helps them to retain their muscle mass as they lose weight.  

We recommend going for a high-protein diet (minimum 30% in kibble and 8% in wet food) for optimum weight loss and health. It’s best to use real meat that hasn’t been overly processed or had any artificial flavors or preservatives added. 

Carbohydrates 

Cats don’t need huge amounts of carbohydrates in their diet, especially if they’re trying to lose a few pounds. The best cat food for overweight cats will avoid carbohydrates in the main ingredients. The carbs your cat does eat should come from healthy sources such as fruit, veggies, and brown rice. 

Taurine 

Taurine is an essential amino acid that’s needed for heart muscle function as well as to aid digestion. It helps to boost metabolism and maintain a healthy weight.  

Omega Acids 

There are such things as good fats – and omega acids are one of them. These fatty acids help with skin and coat health and are a really important part of your cat’s diet. Even healthy cat food for overweight cats should include nutritious fats. 

Fiber 

Fiber is a great way for your cat to feel full and boost digestion. Your pet will be able to absorb more nutrients out of the food whilst consuming fewer calories. 

Vitamins and Minerals 

You should really be buying cat food that has complete and balanced nutrition. Cats need lots of different minerals and vitamins at different stages of their life (kitten, adult, nursing, senior) and the best food should cater to each. You shouldn’t need to supplement any of the most important ones.  

Calories 

Your cat’s calorie intake really depends on how big they are, their activity levels, and their stage of life. On average, cats need between 200 and 300 calories per day. 

Before reducing the calories in your overweight cat’s diet, speak to your vet. They can come up with a realistic plan based on your cat’s weight and tell you how many calories you should be aiming for every day. 

How to Transition Your Indoor Cat to a Weight Loss Food

Whenever you change your cat’s diet – whether it’s from a high-calorie to a low-calorie one, kibble to fresh, or simply changing brand – it should be done slowly. Changing too quickly could put your cat off the new food or upset their stomach. 

Most brands recommend mixing the new food in with the old. The recommended percentages are: 

Days 1-3: 75% old food, 25% new food 

Days 4-6: 50% old food, 50% new food 

Days 7-9: 25% old food, 75% new food 

Day 10: 100% new food 

Some cats may take longer to get used to the new food than others. And that’s OK! Just take your time and don’t rush them into eating.  

How can you tell if your cat is overweight? 

There are a couple of ways of finding out whether your cat is overweight. The first is just to look at them! That may sound obvious, but is your kitty looking a little chubbier than they were a few months ago?  

Another good way is to stroke your cat and gently squeeze its sides. Can you feel ribs? If you can’t, it may be because they’re a little on the heavier side. If you notice your cat sleeping or generally moving less, this may also be because they’re larger than they were.  

However, the best way to know if your cat is overweight is to get an expert opinion. Your vet will be able to tell you how healthy they are and come up with a plan to lose the weight if need be.  

What is the ideal weight for a cat?

The average domestic cat should weigh around 10 pounds, but this can vary a lot depending on the breed. If your kitty is particularly big-boned, they may weigh more and still be completely healthy. 

Final Thoughts 

Weight gain can be a real problem for indoor cats. There are many reasons why the scales are going up but a big one is overfeeding them or feeding them lower-quality food. All of the best cat food for overweight indoor cats on this list is nutritious, low in fat, tasty, and designed to help your cat lose weight.
