Here is Our Guide To Chicken-Free Cat Food

How to Put Weight on a Cat

Having an underweight cat with an unstable appetite is sad and frustrating. The owners have many concerns and don’t know how to put weight on a cat. We’ve rounded up some tips that will help you fatten your cats up to a healthy weight.

  • Choose food with a high protein content

High protein content in cat food for weight gain is a must-have! Enough protein helps your cat build lean and strong muscles, and gain weight naturally.

  • Use tasty treats

Treats promote better eating habits. These treats can be of various types and sizes. You should find the one, which suits your cat best of all. However, don’t forget that treats should make up a maximum of 15% of a cat’s daily calorie intake. They are rich, delicious, and oftentimes, cats prefer them over their regular food. If you pamper your cat with treats often, it can refuse eating regular food, so be cautious.

  • Make sure your cat is physically active

Physical activities are paramount for cats not only because they make cats happy, but because they stimulate appetite. A sedentary lifestyle makes the cat apathetic, inactive, and indifferent to food. This can result in many health problems. To encourage physical activity, use toys for cats, ropes, balls. Play together with the cat so that it runs, jumps, and moves a lot. After these exercises, your cat will be happy to replenish the necessary vitamins and minerals.

  • Use wet food in a combination with dry food

Your cat’s diet should be varied. So, it’s a good idea to use wet food alongside dry food. Wet food is less rich in calories, but it can provide necessary moisture.

  • Try different feeding practices

In order to make your cat gain weight, it’s a good idea to stick to free feeding. Make sure food is available 24/7 and the cat will eat whenever it wants. Another practice is feeding multiple servings. It will help your cat consume a necessary number of calories.

  • Add some moisture

If your vet approves, then add a small amount of water to soften food. Besides, you can also add calorie-rich ingredients to soften the food. For instance, go for kitten milk – it is safe for cats and high in calories – this is exactly the cat needs!

  • Consider adding supplements

If your cat doesn’t gain weight fast enough, you may add some vitamins to its daily meal. There are some vitamins (Vitamin B, C, E) and minerals (zinc, calcium) that can help your cat regain its vitality. But before doing this, consult the vet.

  • Change the environment

Your cat can be stressed out due to some changes in the environment such as changes in living space, new and loud noises, other pets. If this is the reason for a lack of appetite, then eliminate the irritants or acclimatize the cat.

Reasons For Weight Loss

The reasons for weight loss may be different, including some medical problems. So, you should have your cat checked up by a veterinarian. The underlying problems can be:

  • Aging. Senior cats tend to lose weight with age;
  • Neutering. Studies show that neutered cats have a lower metabolism and require fewer calories;
  • Stress and anxiety lead to weight loss;
  • Kidney disease, caused by bacterial infections. Such symptoms as increased thirst, more frequent urination, digestive problems, and behavioral changes are common for kidney disease;
  • Liver problems;
  • Diabetes has such symptoms as excessive urination, extreme thirst, weight loss despite an increased appetite;
  • Heart disease.

What to Look for in Cat Food for Weight Gain

Nowadays, there are many cat food brands that offer balanced blends of nutrients, vitamins, and minerals that aid in digestion, radiant appearance, and strong muscles. If your primary goal is to make your cat gain weight, then always consider the nutrient analysis. Thus, the food with about 30% of protein suits you best of all. Protein is important for mass gain, muscle growth, and consuming enough protein on a daily basis will help your cat gain weight naturally.
