Whenever a cat shows signs of illness, people go on the internet to find out what they can use of their home remedies to treat their cats. Here are the reasons why you shouldn’t give human medicine to cats.
Human Medicine To Cats: Toxic
Most human medicine is simply toxic to cats. That is the main reason why you shouldn’t give human medicine to cats. Toxic matter means also that it could potentially kill your cat.
Many things that is alright for us humans to eat or take is poisonous to cats and human medicine is definitely no exception to that.

For example, something like ibux/ibuprofen, a common Non Steroidical Anti Inflammatory Drug used to ease fever, muscle pain and inflammation is in small dosage deadly to a cat. It isn’t all that great for us humans either, but that is offtopic.
Internet Resources About Human Medicine To Cats
“There is many internet resources for giving human medicine to cats?! Why can’t I just follow their instructions?!” you might ask.
There are certainly chances that some medicine might work for a cat, but it is very specific to what cat and what medicine and in what circumstance. Most resources out there on the internet do refer to dogs and say also that it is often highly toxic or deadly to cats.
I would even deadvice to follow these resources on the internet for your dog if you have one. I am not saying that they might be wrong, but the dosage of these medicine is so difficult to determine for the average person. They give you info like you can give one teaspoon every 20 pounds or a certain amount of milligram per kg or per animal (dog/cat).
It is very hard to weigh or measure these medicine, let alone know the exact weight of your pet. Certain dog races or cat races might also be more susceptible for one type of medicine or the other.
On The Topic Of Natural Medicine
There is also a lot of information on the internet on natural medicine. Although I am pretty sure there is alternative or natural medicine that can perfectly work well for your cat, I advice you to be extremely careful. My experience from the past years is that there is a lot of stuff written on the internet. Not just stuff, but advice from this website about one thing and the next saying that that stuff would be the worst for your cat and that you should instead use something else.
You can guess it, there is a lot of marketing going on and there is little time spend on proper research where it is ensured that the medicine will work for all cats.
Perhaps one can be lucky with dogs, but unfortunately are cats way more sensitive than dogs in that they cannot handle a lot of the natural things. For example are most herbs and oils toxic to them. Cats do not have the same type of liver system as we humans or dogs have and are therefore not able to clean out the body fast enough of things that might be harmful for them if it stays too long in the body.
Another thing that will always be a problem with natural medicine and natural remedies, is that it might work for one breed, while it is potentially dangerous for the next.
Essential Oils
To give you a few examples, I have seen websites write about using therapeutic grade essential oils on your cat. Some write about applying a solution on the skin of cats, where others talk about using diffusers.
When even humans can potentially get problems with their skin, because of directly applying the oils to their skin, why should it work better on a cat?
Unfortunately it is the same story of their liver once again. Cats are unable to get rid of the matter in their bodies and liver failure or liver damage is a direct result of that. While it might look like your cat is fine at first, the damage might already have been done and the result of that comes a bit later.
There is possibly one or two types of oils that might be okay to your cat, but I would simply not take the risk. If anything, you should probably ask your veterinary about it.
So if you care about your cat, do not use diffusers, essential oils, incense’s or essential oil candles in the same room where your cat resides. It is okay to use it in the room when they are not there, but make sure you properly ventilate the room before they get back there.
Best Advice: Contact Your Veterinary
I really de-advice to go for home remedies for your pets. I also really deadvice giving human medicine to cats. You have most likely little clue what is really going on with the health of your pet and you wouldn’t know what is harmful to your pet. Instead of helping your cat (or dog), you might be making them more ill or worse. Also note that medicine designed for dogs, should not be given to cats either.

It will safe you a lot of stress to go to the veterinary with your pet and you get the advice you need. They will know ultimately best. In some cases they can advice you to take a certain human medicine perhaps, but it shouldn’t just come from the internet. At least your veterinary can properly measure the weight of your cat, assess whether your cat breed can handle the medicine at all and advice you the proper dosage.
In most cases veterinaries will give you a note to pickup proper cat medicine at the apothecaries. The medicine made for cats is already in the right dosage and format and has a set of easy to understand instructions for you to understand.
Even if your cat is perfectly healthy, it can be a good idea to visit the veterinary once a year with your cat. A yearly checkup makes sure that you stay up to date on their health. The vet usually helps the cat with staying healthy and also keeps a log of the health status of your pet. If problems occur later on in their life, you will be able to see where things went downhill or got better.

Hi Steven,
I seen your post across Google and read your title – and my first thought was, why in all the Earth would you consider giving human medicine to cats?! I have never heard of this but then through the vast unfamiliarity of humanity – anything is seemingly possible! I am pretty stunned to be honest people would do this. Take your cat to the vet – its that simple.
I am delighted to see you have alternatives to the other option and I believe people will realize Google don’t have all the answers, well, lots of them anyways, but we must understand some recommendations online are opinion based! Here is where you can’t sue someone if you hurt or kill your cat by giving them something you should not be medicating them with.
I am still stunned LOL!
Thanks for this illuminating article Steven.

Hi Philip!
Thanks for your comment and for clicking through. I was as perplexed and stunned as you were Philip when I was researching the matter. It is quite crazy what people do with their pets. I am sure they meant it well, but oh dear it can hurt their cats so badly.
It’s best to use Google to find a Veterinary near you, instead of finding all the alternative ways of treating your cat, that might harm your cat in the process.

Very good advice. I have never been brave enough to even think I could figure out what to give a cat. The vet knows what the animal needs and how much. Thank you for telling people not to try natural things. I had one cat that really wanted to eat a houseplant that was listed as a poison if eaten. I threw the plant out. It was not worth the risk.
Hi Lynn,
I am happy to hear that you agree with me on the human medicine and natural medicine not to be used on cats. It is just better to stay with the veterinary than to self-diagnose and self-treat your cat.
Some plants are really toxic and some human foods are toxic too, so you need to prepare your home if you want to have cats. There are however a couple of safe plants for cats, you can still have to colour your house with.
Thanks for your comment Lynn and hope to see you back!
