    Smalls Cat Food isn’t found in stores. This is a subscription meal service for cats that sends healthy food right to your door. The company uses high-quality ingredients, like protein from real animal sources, vegetables, vitamins, and minerals. You can choose between several fresh recipes, and they are all completely customizable.

    There are several recipes with various protein options, but a popular pick is the Small Fresh Bird recipe. Chicken is the main protein source, with meat from the breast, liver, and heart. Green beans, kale, and peas are added for nutrients and healthy carbohydrates. The recipes are high in protein and low in fat, making them helpful for cats that have a few pounds to lose. The lean protein helps build lean muscle while giving your cat energy to run and play. This food contains no artificial fillers or additives, although trace amounts of vegetable oil are used in a few recipes. We feel Smalls is the overall best cat food for weight loss.

    The ordering process is simple. Just head to the website, and fill out a short survey about your cat to get started and see which recipes would be best for them.

    While the subscription service is convenient, it does mean you’ll need space in your refrigerator to store the food if you choose the fresh recipes. The food is also more expensive than some other high-quality brands.

    Buyer’s Guide: Choosing the Best Cat Foods for Weight Loss

    Why Is a Healthy Weight for Your Cat Important?

    Keeping your cats at a healthy weight might not seem like a big deal initially. After all, who doesn’t love a big chubby cat? Even though it might be adorable to squeeze their balls of fluff, it’s best to help them maintain a healthy weight throughout the duration of their lifetime.

    This can get a little bit more challenging as they start to age and become less active. Also, once a cat is spayed or neutered, they tend to gain weight as well.

    Health Issues Associated with Obesity in Cats

    There are a wide variety of problems you can face when your cat is obese. These problems can develop over time, or the onset may be much faster. Some issues require treatments, medication, and other potentially expensive management methods. It might also decrease the lifespan of your cat.

    Some of these health issues include:
    • Diabetes
    • Heart failure
    • Infections
    • Urinary bladder stones
    • Hepatic lipidosis
    • Osteoarthritis
    • Hypertension

    Spayed or Neutered Cats & Weight Gain

    Once your cat is spayed or neutered, weight gain is very common. That is because these procedures cause a cat’s metabolism to slow down, causing body fat to be distributed to the body, especially in the abdomen.

    It’s very easy to tell when a cat is fixed because a large portion of their body weight gravitates toward the infamous fat pouch on their bellies.

    Even though some weight gain is expected, it can be really easy for your cat to pack on the extra pounds. If their activity levels are also decreasing, it is incredibly important to get a handle on offering extra calories.

    Free Feeding vs. Scheduled Feeding

    Free feeding is basically when you place food into a bowl and allow your cat to eat at their leisure whenever they feel like it. Scheduled feedings are routine, set at specific times throughout the day.

    If you’re trying to get your cat on a diet, free feeding is not a good option. There’s no regulation here as far as caloric intake is concerned. Scheduled feedings create much more of a routine and allow you to closely monitor your cat’s precise intake.

    Weight Control for Cats

    When it comes to controlling a wait, there are several different aspects that come into play. Obviously reducing calories is one of the main ways manufacturers formulate these recipes. There are certain ingredients that can boost metabolism while reducing weight.

    • L-carnitine – This chemical is made in the brain, liver, and kidneys. It helps the body turn fat into energy.
    • Fiber  – Fiber helps to speed up and regulate the digestive tract, making sure that the digestive system is not sluggish.
    • Prebiotics & Probiotics  – Prebiotics and probiotics work hand-in-hand. Pre-biotics lay the foundation in the gut to help probiotics flourish, growing healthy gut bacteria.
    • High Protein – If your cat is losing weight, they need to keep their lean muscle mass intact. Often when calories are cut in a recipe, the protein is up to make sure that your cat is getting enough protein to rebuild their muscles.

    It’s best to discuss your cat’s weight loss goals with your vet so you can find the best diet.
