Benefits of Supplements for Senior Cats

Supplements can help fill in nutritional gaps and support various bodily functions, including joint health, which is probably the most common supplement for cats, immune system support, kidney and urinary health, and digestive function.

Senior cats may experience cognitive decline, which can lead to confusion and disorientation. Supplements containing antioxidants and omega-3 fatty acids can help improve cognitive function and reduce the risk of cognitive decline. 

Overall, supplements can help senior cats maintain their health and improve their quality of life. However, it’s important to consult with a veterinarian before giving your cat any supplements to ensure they are safe and effective.

Essential Supplements for Senior Cats

Supplements for senior cats that can help them stay healthy and active and enjoying their life for a longer period of time. Don’t look at this as a checklist where you offer Kitty everything. Kitty will probably rebel.

Choose what is most important to Kitty’s health at that particular time. Look for a combination product like Pet Wellbeing Spark that adds probiotic, enzymes, antioxidants, and more. Add and subtract as needed or recommended by your vet.

Joint Health

Senior cats are prone to arthritis and joint pain, which can make it difficult for them to move around. Considering that cats are living longer now, but 60% of cats show some signs of arthritis as young as 6 and 90% of cats over 10 are diagnosed with joint pain, it is no surprise that supplements for arthritis and joint pain is the number one reason cats take supplements. 

Products containing glucosamine, chondroitin, and MSM can help reduce inflammation and improve joint health. Bromelain (a pineapple enzyme) and Boswelia (an herbal)  also are ingredients that help with inflammation and pain relief for joint relief for cats.

My favorite hip and joint supplement for senior cats is Cosequin. Treeno was on it for years before we had to add pain relief medication for him. If you are looking to prevent problems with a helpful supplement, look at 1-TDC. Several of my cats take it.

Probiotics

Senior cats can have problems absorbing nutrients from their diet. Aging cats may also have reduced digestive system function and be prone to constipation or diarrhea.

Probiotics are used for management of cats with acute or chronic gut disease. Probiotics are beneficial bacteria that can help improve digestive health and boost the immune system.

Hairballs may be more of a challenge for a senior cat to process, leading to constipation or vomiting. 

Your kitty with the ‘cast iron stomach’ that could eat everything, never required a transition time with a diet change, scarfed all sorts of things off your plate, may now develop stomach complaints when he indulges in dietary excess. A cat that is under stress can also develop digestive distress.

If Kitty is taking antibiotics for dental infection, upper respiratory problems or a urinary tract infection, something senior cats often suffer from, he is also likely to contract a raging case of diarrhea as the medication kills off both good and bad bacteria in the gut. 

There are several popular brands of probiotics for senior cats. My vet prescribes Proviable-DC which is best for a short term intervention when Kitty has digestive distress. It comes in a sprinkle capsule form and a paste for the first couple doses in managing diarrhea. We’ve used it with good success with a cat with IBS and several times with kitties with antibiotic induced diarrhea.

Fortiflora is a popular choice for a cat probiotic.  It is also a powder you add to your furbaby’s food. It is very palatable for cats and can stimulate their appetite as well as curing stomach problems and boosting their immune system.

Digestive Enzymes

Going along with probiotics, digestive enzymes can help senior cats with digestive issues such as constipation, diarrhea, and vomiting. These enzymes can help break down food and improve nutrient absorption. Some products combine probiotics or prebiotics along with enzymes. These are intended for longer term use than Fortiflora or Proviable. 

I was lucky enough to win a package of InClover’s supplements. They have a digestive aid product called Optagest. It is a powder containing digestive enzymes and prebiotics to encourage growth of good gut bacteria. I tried it with all my cats, not just my seniors. Even my pickiest boy didn’t object to having it added to his food (as long as he didn’t see me do it.)

Hairball Remedy

Hairball remedies are an important supplement for senior cats with hairball problems. These remedies can help prevent hairballs from forming and make it easier for cats to pass them. The typical remedy is a paste form or treats. It can also help with general constipation.

Antioxidants 

An antioxidant supplement helps support normal body system functions in aging cats and eliminate damaging free radicals, reducing their negative effects in the body. It boosts Kitty’s immune system, prevents cellular damage, and keeps her energetic as she ages. Antioxidants are also useful for supporting joint health, cardiovascular health, and balancing Kitty’s blood sugar.

One of my favorite product lines, Pet WellBeing, has two products that provide antioxidants and immune support for your senior cat: Core Immune Care powder and Life Gold for Cats liquid. I haven’t tried the Immune Care yet, but I have used Life Gold with several of my senior cats. I always appreciate a liquid because for me it is the easiest way to get a supplement into my senior cats.

Omega Fatty Acids

Omega fatty acids can help improve skin and coat health in senior cats. They can also help reduce inflammation overall and improve joint health. Typically, this comes in the form of a fish oil supplement. Omega’s can help with joint care, but senior cats also benefit from the cardiovascular health boost and cognitive support. 

All cats get skin and coat benefits from adding an Omega supplement. My Ryder, who I brought home from the shelter with anemia, significantly underweight, and a terrible coat, now has a lovely, thick, soft coat.

There are a lot of Omega supplements out there. I recommend PetWellbeing, but it is just because I love their products. Anything you choose should provide the benefits you want for your kitty. 

Hydration Support

Senior cats become dehydrated more easily than younger cats. Supplements such as electrolyte solutions and water additives can help improve hydration and prevent dehydration. HydraCare, KittyRade, or Petralyte can help a cat with kidney issues, that isn’t drinking enough for whatever reason.

Overall, it is important to consult with a veterinarian before giving any supplements to senior cats. A veterinarian can help determine which supplements are appropriate for your cat’s individual needs and health concerns.

Choosing the Right Supplements

When it comes to choosing the right supplements for senior cats, there are a few factors to consider when selecting supplements for your furry friend. 

Age Considerations

As cats age, their bodies may require different nutrients than they did when they were younger. For example, a geriatric cat may benefit from supplements that support joint health or cognitive function while a mature cat might have a greater need for digestive help or dental supplement.  It’s important to choose supplements that meet your senior cats’ needs. 

Sometimes it is a balancing act. It is so tempting to add everything to Kitty’s plate. After all, we want her to live for as long as possible. 

But is she likely to want to take all those supplements on top of any medication your vet prescribes? Can you mix it all in her food or treats and have her still eat it?  I know in my case, Treeno is NOT going to do that. If I can get a couple things into him I feel lucky. 

So it is sort of prioritizing what he needs the most at this time. Is it arthritis? Is he having a stomatis flare-up?  Do I need to prioritize Johnny’s kidney health and urinary function? And you can change it up.

Dietary Needs

Another important consideration when choosing supplements for senior cats is their dietary needs. If your cat is on a special diet due to health issues, it’s important to choose supplements that are compatible with their diet. For example, if your cat is on a low-protein diet, you may need to choose supplements that are low in protein as well.

Delivery Options

This is a know your cat sort of thing. If your baby will eat anything and has no problem with vitamin type chews then look for supplements that come in a functional chew.

If your kitty wouldn’t touch a functional chew to save his neck like my Treeno then a liquid form might work better. That’s one reason I like the PetWellbeing liquid supplements. I can combine things and dose him with one syringe in the morning and one at night and get several things into him. 

Some cats will take things mixed in their food and others won’t think of eating something you have messed around with. It might taste like vitamins.

Veterinarian Recommendations

Finally, it’s always a good idea to consult with your veterinarian when choosing supplements for your senior cat. Your vet can recommend supplements that are appropriate for your cat’s individual needs and can help you determine the proper dosage.

Some vets are more open to supplementing than others, I feel lucky my vet has encouraged me to try some supplements for my senior cats, and hasn’t told me anything more than “there’s not a ton of science, but it is your money, it might help. It won’t hurt.”

Additionally, your vet can monitor your cat’s health to ensure that the supplements are having the desired effect.

By keeping these factors in mind, you can choose the right supplements to help support your senior cat’s health and well-being.

Monitoring Health and Supplement Efficacy

As senior cats age, they may require additional supplements to maintain their health. However, it is essential to monitor their health and the efficacy of the supplements regularly. Here are some useful tips to help you monitor your senior cat’s health and supplement efficacy.

Regular Check-Ups

Taking your senior cat for regular check-ups with a veterinarian is crucial to ensure that they are healthy and that their supplements are working as intended.

During these check-ups, the vet can perform various tests to determine if your cat’s health is deteriorating or improving. They may also recommend changes to your cat’s diet or supplements based on their health status.

Observing Behavior Changes

As a cat guardian, it is essential to observe any changes in your senior cat’s behavior and health. If your cat is not behaving as usual or is showing signs of pain, it may be time to take them to the vet for a check-up. Some common signs of pain in senior cats include changes in appetite, lethargy, and decreased mobility.

Regularly monitoring your senior cat’s health and supplement efficacy is crucial to ensure that they are living a healthy and happy life. By following the tips mentioned above, you can help your senior cat age gracefully and stay healthy for as long as possible

Summary

Supplements can be a great addition to the diet of senior cats. They can help support their joint health, improve digestion, boost their immune system, and more. However, it is important to consult with a veterinarian before introducing any new supplement to your cat’s routine.

Always choose high-quality supplements and make sure to follow the recommended dosage. With the right supplement and proper care, your senior cat can continue to lead a happy and healthy life for years to come.
