There are many uses for hydrogen peroxide for animal care. Below is a list of some uses for hydrogen peroxide that I’ve heard of, and surely there are many other uses that I have not heard of or thought about. (Some of these I've used, some I haven't.) Please note that the list includes some items under separate headings, down to the very bottom of this page.
Peroxide can be used to clean our furry friends themselves – to clean the fur of cats and dogs. Spray 1% to 3% peroxide onto a clean dish towel, then rub the damp towel on the animal’s fur. Rub in the same direction as if you were petting the animal. Be gentle around ears, and paws, just as if you were petting the animal. Be careful to keep hydrogen peroxide away from eyes.
When I tried cleaning a cat this way, it resulted in a clean fluffy cat! The process seems similar, to me, to using the “spray baths” I’ve bought at the pet supply store. The cat was surprisingly tolerant of the process.
Peroxide can be used to clean stained fur -- such as the condition "Maltese eye stain" -- common in Maltese dogs.
This page has information on using hydrogen peroxide (and other things) to clean stained fur in Maltese dogs.
If you’ve emptied a litter box and find it could use a good cleaning, try one of the following:
This will clean and sanitize your litter box. It should also clear out odors, along with the germs.
(This also works with bedpans and enema parts.)
I have some “ant proof” cat dishes – these have 2 rims with a small gap in between. Have you seen these? The idea is to fill the gap up with water, which keeps ants out. Well, let me say: dry food will fall in there if you use this dish for dry food! And it will get gross quite easily as the dry food breaks down and rots. Yuck. What I do is empty both the dish and the “gap”, rinse it out, and then fill the “gap” in with 3% hydrogen peroxide. Let it sit for a day. (An hour is probably long enough, but I tend to leave things for a day and then come back to them.) Now drain and rinse with water. All clean! Now I refill the “gap” with water (to keep ants out), and refill with food.
It is worth noting that cleaning the house with hydrogen peroxide, rather than chlorine bleach or other toxic cleaners, is also a benefit to our companion animals. Cleaning products can get on their fur – which they will later lick. This means they may ingest a small amount of whatever cleaners you use.
Also, I’ve read that chlorine can smell like urine to some animals. Think about how confusing and upsetting that could be to a cat or dog that is living with this smell!
What about hydrogen peroxide uses to keep your self clean too, when you get scratched by an animal, when you have finished cleaning wounds, or cleaning litter boxes? Many tasks we do in caring for our animals involve contact with germs and bacteria.
Hydrogen peroxide can be used to clean up after these tasks. Just wash your hands as usual, then spray some 3% hydrogen peroxide on your hands, or soak your hands in 3% peroxide for a few minutes. (More information here on uses for hydrogen peroxide for disinfecting your hands.)
If you get scratched by a cat, it is especially important to keep the cut clean. Cat scratches can get some nasty infections. So, hydrogen peroxide can be of special service to you in this regard.
The same applies to getting scratched by a dog, or raccoon,
or any wild animal. If you have the misfortune of being
scratched by any wild animal, hydrogen peroxide is a great
first aid step to take. It will kill bacteria and disinfect
