Hello, this is YUI from Poponeko!
Summer is just around the corner! The number of hot days is increasing, making us wish we could relax with our cats in a cool place.
During this season, cases of feline dermatitis seem to increase significantly.
One particular concern is "metal allergies." Cats can also have metal allergies.
This time, I'd like to introduce some cat collars that are safe even for cats with metal allergies.
Metal-free, for peace of mind

A while ago, I received a message saying, "My cat can't wear a collar because of a metal allergy."
I wasn't aware that cats could have metal allergies. After some research, I found that metal can be an allergen, causing inflammation in the areas it touches.
Cat collars are worn all the time, and metal can come into contact with the skin. So, I decided to make a metal-free cat collar! I immediately started making prototypes.
After trying various metal-free fasteners, resin ones turned out to be perfect, offering both excellent strength and design. Now, cats with metal allergies can wear collars without worry!

Gentle organic cotton for cats

Cat allergies often manifest as dermatitis. It's best to use materials that are as gentle as possible for things that come into contact with their skin, like cat collars.
That's why all our metal-allergy-friendly cat collars are made from organic cotton. They are made from JOCA (Japan Organic Cotton Association) certified cotton fabric, grown without pesticides or chemical fertilizers, so even cats with sensitive skin can wear them safely.

▲ 4 patterns available!
The fabric is smooth and incredibly soft to the touch. The beige color also gives a gentle impression.

Organic Cotton Series for Peace of Mind

Organic cotton is also restricted from chemical treatments such as bleaching, so the natural fluffiness of the cotton is preserved.
The fluffy, moist texture is truly unique to organic cotton. I love it myself.
These handcrafted organic cotton cat collars are very gentle, and many cats love them!
Also, for those concerned about the cleanliness of cat collars, we recommend the "Clenze® x Organic Cotton" cat collar. It has antibacterial and antiviral processing, which helps suppress unpleasant odors even in humid seasons.
If you're concerned about your cat's skin, try an organic cotton cat collar!
