Great for Pet Diapers Too!
Size: Size 1, Unit Count: 128
I have purchased these diapers several times for our special needs Cat. After purchasing one set of Pet diapers that cost a ridiculous amount of money for on,y 20 diapers and pay 25.00, I did what every other pet owner of dogs and cats do. Buy human diapers.
Just for reference the size, small diapers in the pet version equals a size 1 in the human diapers
The only thing you do is cut an upward slit on the back of the diaper that does not have the tape side. Place the slit just below the middle back part of diaper. I cut an inch or so slit. You don’t want the slit to be too big because you don’t want anything coming out of that part ha ha . You’re just using the slit to put the tail through. That’s it
Works like a charm.
Instead of paying $25 for 20 diapers in the pet version we pay $24-$28 for the Huggies version for 128 diapers.
Big difference!
I do not understand why all of the pet version supplements and other products are so much more expensive than the human version of the same exact product.
I don’t understand why the pet companies charge so much but customers will go to other sources to get just as good of a product at a reasonable price.
Thanks again Amazon and Huggies for providing a great product for our special needs cat!

Work 👍 great
Size: Size 1, Unit Count: 128
Diapers work 👌 perfect. I received them a day late & needed them for a baby shower. Amazon Prime stated that I would receive them the next day, Diapers arrived in 2 days. Therefore i went empty handed to the baby shower. Be warned Amazon Prime does NOT always deliver as stated.

Softest diaper ever.
Size: Size 1, Unit Count: 44
I’ve tried almost every brand on the market. I finally settled on these, and they are worth every penny.
Here’s why they stand out:
Absorbency: These are incredible for overnight. No leaks no late night changes
Material & Feel: They are incredibly soft—almost like cloth. If your baby has sensitive skin or is prone to redness, the breathable material makes a huge difference.
Fit: The leg cuffs are stretchy but secure. They dont leave that deep red marks that cheaper diapers do.
Wetness Indicator: The line is clear and easy to see, even through a onesie.
I bought a size 1 for my 9lb baby and it fits perfectly.

Best diaper
Size: Size 5, Unit Count: 84
The only diaper band we ever buy. We’ve never had any blowouts because of it. It’s easy to use and hold up a lot. It’s really soft and doesn’t give any rashes. The material is great. Doesn’t really stop odor not that I expected it.
