You can buy grapefruit seed extract in commercial products such as Nutribiotic®. People say that when it is diluted with water it is an excellent health remedy as it kills a whole host of microorganisms and/or it inhibits their growth. For example, it is said to be a remedy for upper respiratory infections, skin diseases, bacterial infections, fungal infections, parasites and viral infections generally. People say it can be administered internally and applied externally in diluted form.
I am writing this article to flag up this product so that people can assess it themselves. Caution should be applied. When I searched this product on veterinarians’ websites my initial impression is that it is not referred to on these sites. This does not mean that it is no good. It just indicates that it is not recommended by veterinarians although some of them might.
Also, I did some research on this product on the Wikipedia website. The author says that there is no scientific evidence that grapefruit seed extract has health benefits for cats. What the author says is that the artificial preservatives in the commercial products, such as benzethonium chloride have an effect on microorganisms. In other words, the synthetic preservative is the “anti-microbial agent” rather than natural grapefruit seed extract (GSE).
Studies have shown that many grapefruit seed extract products are contaminated with preservatives. A study found that there was no effect on feline calicivirus and feline parvovirus by GSE.
Advocates of the product say that it can also be used to disinfect cages, for example at shelters and breeder catteries. If so, it may the disinfectant qualities of the preservative which is working. I am playing devil’s advocate.
Nutribiotic GSE can also be mixed with other off-the-shelf topical preparations such as shampoos. I’ve decided that it would be unwise to discuss the dilution levels. I’d rather leave that to readers to work out if you believe that there are health benefits for cats but it must be diluted. As a guide: “three to 15 drops of GSE added to pet food or water. One or more times treatment per day, depending on size of critter…”
One cat owner said that she had struggled to cure her cats’ respiratory infections and her veterinarian had failed to assist so she relied upon grapefruit seed extract and had success she claims:
I use two drops per day per cat in canned food with great results….Now this was after countless vet visits, bouts with amoxydrops, and clavamox and even baytril. Nothing was working. So I started using this, in their canned food and also dropping it into the water fountain, about 6 drops every time I scrubbed the bowl out. Within one week, I started seeing differences in the kittens first, then with the cats (hissy on the cat site).
Another product on the fringes of cat health treatments is L-lysine for viral infections.
Haley said in a comment (see below):
“CAUTION. Grapefruit seed extract is TOXIC TO CATS!! After reading about the miraculous benefits of GSE I started giving it to my cat who had a nasty upper respiratory infection. Well after about 10 days he started eating less and becoming less active so I continued giving him the GSE thinking the virus was coming back. I was wrong! It was liver toxicity symptoms. Soon he started shaking, throwing up and he would just sit in one place balled up looking at the ground. Liver numbers not normal. Please learn from my mistake and don’t give cats grapefruit seed extract!”

Good luck. And thanks for visiting.
anything is toxic to cats if you use it wrong…….. also, in my experience, vets barely know wtf theyre doing. at least in my town, i am currently looking to find a vet who isnt a total moron. they tell me all kinds of shit to get more diagnostics and then after 2000 dollars, tell me its nothing. im not even kidding. and when it is something they arent willing to do fk all. so…. i dont get it. i am not going back to one and am on the search for a homepathic/natural veterinarian, does one even exist????
After reading the comments, sounds like using GSE on cats should be just a one time deal for maybe worms, I know many of the deworming meds doctors give to cats are a one time thing than you wait 20 days and do it again. Apparently dogs are more tolerant of GSE.
Susie, it may be useful, first, to get to the bottom of his over-grooming. In 90% of the cases of over-grooming, it is due to stress. This is not a criticism of you. It may be because he is a nervous cat or there is something going on which causes him to be anxious. I think it would be very useful if you could do some detective work and find out what it is. If you like you could pass that information onto me and I’ll will do some work on it which may help him. What I’m advocating is taking proactive steps to stop his behaviour rather than reactive steps which is what you are suggesting. I don’t think coconut oil would help the area to heal. I must say that it sounds bad if he has over-growned so much that he had injured himself.
my cat will not stop licking himself! he has always been a groomer, but not in his old age is licking raw spots. do you think that the gse and coconut oil applied will help to heal?
Regarding Grapefruit seed extract in cats: be very careful of what you read online, as I have seen some confusion of GRAPESEED extract (harmless) with GRAPEFRUIT SEED EXTRACT (possibly toxic).
