Have you ever found yourself standing in the pet food aisle at the supermarket to buy cat food and don’t know whether to get the senior cat food or the regular cat food? Of course, you want to provide the best diet for your young or senior cat, but what if there is something in the senior or regular feed that is better for your cats? Which one is the best choice? What is the difference between senior cat food and regular cat food?

Senior cat food contains fewer calories and protein than regular cat food due to older cats being less active than younger cats. As a result, the phosphorous levels in senior cat food are less and do not compromise the function of their liver and kidneys. It is also softer and specially designed for a senior’s brittle teeth.

Many cat owners feed their senior and adult cats the same food; however, their dietary needs are different. Therefore, it is essential to ensure that they receive the necessary nutrients depending on their age. This article will discuss the differences between senior cat food and regular cat food and what you need to know for your cat to have the best, healthiest and happiest life.

Is Senior Cat Food Necessary?

As a cat ages, his dietary needs change. Some ingredients present in the regular cat food are no longer required or are only necessary in smaller doses. Senior cat feed is needed because the contents assist their teeth, aging joints and help to ensure that they maintain a healthy coat and strong immune system.

It is always a good idea to have a veterinarian’s opinion and expertise on what is or isn’t good to feed your cat. The most important thing is to ensure that your cat has a balanced diet.

Long-term feeding of dry cat food can lead to renal failure in cats. Canned or wet cat food contains water; therefore, cats on a dry-food-only diet take in only half the amount of water as opposed to a balanced diet of wet and dry food.

If you are only feeding your cat dry food, you need to consider getting some wet food and alternating between wet and dry during the day. Cats that only eat dry food can become dehydrated, which places stress on their kidneys over time.

What Are The Benefits Of Senior Cat Food?

Lower Calories – Senior cats that have a controlled or low-calorie diet are less likely to become obese. This lowers their chances of developing high cholesterol, and they won’t have excessive weight on their aging joints. Veterinarians insist that it is imperative to feed senior cats an energy-dense diet to maintain a healthy body weight.

Antioxidants – The enhanced level of antioxidants in senior cat food helps strengthen a senior cat’s fragile immune system.

Efficient Digestible Ingredients – As your cat gets older, they require a diet that is easier for their bodies to digest. This helps to prevent toxin build-up in the cat’s colon and supports their overall gut health.

At What Age Should You Switch Your Cat To A Senior Diet?

Cats are considered to be seniors between the age of 7 – 10 years. This is when it is time to think of adjusting your cat’s diet from regular cat food to senior cat food.

Senior food is higher in carbohydrates and lower in protein and fat, accommodating their decrease in physical activity.

Can Senior Cats Survive On Regular Food Only?

According to the United States, Food And Drug Administration, regular cat food labels should contain +/- 22% protein and +/- 8 % fat. Unfortunately, senior cat food only contains 18% protein and 5% fat. If younger cats don’t get enough protein, they are more likely to develop various health conditions.

Regular cat food contains more minerals and vitamins because younger cats are still growing and need the additional phosphorous, calcium, and other nutrients to ensure healthy bones and teeth.

Regular food contains 30% more calories than senior cat food, so if an old cat were to live on regular cat food only, chances are they will become overweight, sedentary, sickly. In addition, they will be more prone to diseases and illnesses due to a weakened immune system

Senior food is easier for cats to digest to accommodate their changing needs as they age. Therefore, if you had to select one type of cat food appropriate for all your cats to share, the best choice would be the senior cat feed.

With that being said, you need to bear in mind that kittens require a different diet from regular or senior-aged cats. This is because kittens are still growing and need a sufficient supply of nutrients to prevent compromising their health and physical development. Therefore, kitten food contains more protein, vitamins, and calories than food for older cats.

Is It Safe For Cats To Only Eat Dry Food?

Protein and caloric content are essential, but there are a few more factors to consider when selecting the best food for your cat.

The protein content listed on wet food could indicate 10-15%, while the label on dry food will show a 20-30% protein content. Therefore, you must feed your young or senior cat the correct balance between wet and dry cat food.
