Reasons your cat may need a high calorie diet
There are several reasons why your cat may need a high calorie diet. Sometimes it’s due to old age and other times, because of health problems that caused a decline in weight.
However, if you notice that your cat has lost a significant amount of weight, consult your vet. They’re likely to need an examination to rule out diseases.
For pregnant and nursing cats, high calorie cat food helps keep them healthy and capable of producing enough milk.
How do I know I have an underweight cat?
According to the ‘Body Condition Score’ chart for cats, a cat is underweight when you can no longer feel any fat when touching your cat’s body. Their ribs are clearly observable by sight alone on short-haired cats. They also have a prominent abdominal tuck.
The average cat weighs ten pounds but your cat’s breed will dictate their appropriate weight.
Why do cats become underweight?
Cats can become underweight due to several reasons including many health problems like hyperthyroidism.
When your cat approaches their golden years, health problems are inevitable. Weight loss also becomes more prominent due to issues like arthritis. Take note when your cat’s behavior changes as weight loss can be an indication of numerous problems. You may need to move their water and food dishes closer to where they hang out if their joints are achy!
Also, about 30 to 40 percent of cats aged 10 to 12 years old have problems digesting fat and protein. Weight loss in older cats is often attributed to chronic renal disease, diabetes mellitus, hyperthyroidism, inflammatory bowel disease, exocrine pancreatic insufficiency, and dental problems.
If you notice that your older cat is losing weight, contact your vet.
Diseases and health problems of underweight cats
Cats tend to hide their pain. If your cat is vocalizing a lot, hiding, and not coming out then you should see your vet as there may be a health issue.
We’ve listed a few below:
Diabetes Mellitus is a serious and complex disease. And sadly, it isn’t uncommon in cats. Between 0.2 and 1 percent of cats in the general population are believed to suffer from diabetes.
Diabetes affects the hormone insulin. This is a condition in which the body cannot properly produce or respond to the hormone insulin. This results in elevated levels of the sugar glucose, which is the main source of energy for the body.
The Cornell Feline Health Center tells us that the cells in a cat’s body need sugar in the form of glucose for energy. And glucose in the blood needs insulin. Insulin signals when the time is right to absorb glucose. By absorbing glucose, cells get the vital fuel they need and lower levels of glucose in the blood.
Although experts are yet to find all the possible causes, carbohydrates could be a culprit.
With this in mind, it’s important that you treat your cat’s diabetes.
This disease can ultimately lead to a coma or even death in severe cases.
Being obese increases your cat’s chances of getting diabetes. If you notice any of these signs or other behavioral changes, consult your vet!
Hyperthyroidism is quite common in cats. It generally affects older kitties.
Overproduction of thyroid hormone or hyperthyroidism is common when cats get older.
It occurs when a nodule on the thyroid gland overproduces thyroid hormone.
Some possible factors include excesses or deficiencies in the diet. It could also occur from chronic exposure to environmental toxins. These can come from either the environment or food.
Because of the influence of thyroid hormones, this often leads to other problems and unexpected sudden weight loss is at the top of the list.
Check out our article for a list of the best foods for cats with hyperthyroidism.
Chronic kidney disease
Chronic kidney disease in cats is a persistent loss of kidney function.
The kidney is in charge of many things. Most importantly, it filtrates the blood and makes urine. If kidney cells are sick, they may be able to come back and return to function. If the kidney cells have died, they cannot be replaced.
So, when the functions of the kidney decline, it can cause a variety of health problems. This includes weight loss.
Cancer can have devastating outcomes for both humans and animals.
Weight loss is one of the first symptoms when it comes to feline cancer. You should also look out for lethargy, loss of appetite, unusual hiding, and unexplained weight loss. Feeding a pet with cancer is also a balancing act. The goal is to provide optimal nutrition to support the immune system.
Cats can hide symptoms of dental disease for months or even years. Sometimes owners that did not realize their cats had dental disease cannot believe the change for the better after a dental procedure. For cats especially, it is very important they have regular oral exams by your vet.
Focusing on preventing advanced periodontal disease in your pets is extremely important. Our pets need regular dental cleanings and their teeth should be brushed daily!
Sometimes, a change in the environment can cause a shift in your cat’s eating habits. This usually includes stress, anxiety, or depression.
If your cat undergoes psychological stress, it may stop eating. This will eventually lead to weight loss so you’ll need to watch your cat’s behavior carefully.
Other reasons may include excessive noise, other animals, and dirty food dishes. Clean those food bowls daily!
How to help your cat gain weight
If you fear that your cat might be underweight, we recommend that you first contact your vet. You need to confirm there are no underlying medical issues and talk through a plan with your vet to help them gain weight.
Try these quick tips below with your vet’s guidance:
- Place the food bowl in a quiet spot: If your cat is nervous, make sure that their food isn’t near a scary object like the dishwasher. Feed all your animals separately so they’re not competing with each other.
- Vary their diet: Whether your cat eats kibble or canned food, mix it up once in a while. For instance, if they eat dry food daily, replace one meal with a canned option. Consider toppers for their diet. You can also make homemade cat food.
- Serve more meals or try free-feeding: Most cats prefer to graze during the day. To help your cat gain weight, try giving them access to smaller portions throughout the day. Or simply leave a bowl of their favorite kibble for them to nibble on as they like. Consult with your vet beforehand to determine the diet you should be offering.
- More cats mean more food bowls: If you run a multi-cat household, all your cats need to have equal access to food. Sometimes, a more dominant cat prevents others from eating. Always have an additional bowl in a more secluded spot. If one of your cats is a bully, consider confining them during mealtimes so that every cat gets their fair share of food.
- Heat the cat food to make it more palatable: Giving their food a quick turn in the microwave increases its aroma. This may make your cat more inclined to eat. Be sure that you use a microwave-safe bowl and avoid giving it more than 10-seconds.
- Add liquid to the cat food: Try applying a small amount of chicken broth or fluid from a tuna can. This may enhance the flavor and aroma.
What can I give my cat to gain weight?
Once you’ve ruled out health problems, the next step is to look at your cat’s diet. We recommend that you talk with your vet to create a comprehensive plan.
Opting for high calorie foods for cats is probably the best way to help your cat gain weight.
With dry cat food, your cat receives a lot of calories per mouthful. That said, it depends on whether your cat wants to eat it.
Fortunately, there are plenty of high calorie cat food options, both dry and wet. For canned or wet food, try opting for paté textures as opposed to the more soupy, gravy-filled options. With 78 percent moisture, canned food is wonderful for cats that are dehydrated and many are!
Another way to help your cat gain weight is by offering healthy treats and snacks.
Keep a small bag of special food or treats with you. Offer them some pieces in between meals or during snuggle time. Your cat will probably enjoy this but remember to cut back once they’ve reached a healthy weight.
3 tips for choosing the best high calorie cat food
Below are three tips to help you find the best high calorie cat food for your kitty.
1. Give them what they love
When you’re looking for cat food for weight gain, it’s important to prioritize their preference since cats are picky. Find cat food they find palatable but within their dietary requirements.
You may also want to consider the type of food—wet or dry. If your cat prefers one over the other, it’s probably best to go with what they enjoy. Changing up the type of food might make them feel less inclined to eat it.
Looking at cat food labels can be confusing! The AAFCO now has guidelines on what brands must include and what claims they can’t make.
- Always read the cat food label: There is a system for listing the ingredients on your cat’s food label, and understanding it will help you pick the best ingredients.
- The FDA mandates that ingredients must be listed from most to least based on their weight.
- The majority of your cat’s food is made from the first few ingredients listed, so be sure they aren’t fillers. Instead, look for whole foods like chicken or rabbit.
Animal protein and fat are crucial ingredients that should be included in your cat’s food. Because your cat is an obligate carnivore, it needs nutrients like taurine.
However, if your feline friend has lost weight, we recommend asking your vet about the best choices. Focus on fat content.
If you want some help, we recommend checking out the AAFCO nutrient profiles. Here, it shows the recommended percentages.
3. Consider the brand
Be wary of low-quality commercial cat food brands. These are often foods with ‘fillers’ and other low-grade ingredients.
You see, your cat will need to eat twice as much to make up for the lack of nutrients. This means that you’ll be buying food more often than with a quality brand and you’ll end up spending more.
If your cat has a medical issue they’re likely to need a special diet.
