There are the following differences between pet potty pads and adult underpad:
In terms of usage
- Pet potty pads: Specifically designed for pets, they are used for the daily urination of pets, helping them develop the habit of excreting in a fixed area, keeping the indoor environment clean, and preventing pet urine from soiling floors, furniture, etc.
- Adult underpads: Mainly used for adult urinary incontinence, women's menstrual periods, postoperative care, etc., providing hygiene protection for adults who have difficulty moving or cannot control urination independently, and keeping beds, seats, etc. dry.

In terms of size and shape
- Pet potty pads: The sizes are relatively flexible and diverse. There are small pee pads suitable for small pets such as hamsters and rabbits, as well as larger ones suitable for large dogs. The shapes are usually mainly rectangular, but there are also circular or irregular ones to fit different pet cages or resting areas.
- Adult underpads: Generally larger in size, its shape pays more attention to conforming to the human body's physiological curve to fully cover the excretory parts of the human body and provide a better user experience.
In terms of absorption performance
- Pet potty pads: Generally, they focus on quickly absorbing urine to prevent it from spreading and flowing on the surface, but the total absorption capacity is relatively small, which can meet the urination needs of different sized pets.
- Adult underpads: They need to have a stronger total absorption capacity to deal with larger amounts of urine. At the same time, the requirement for keeping dry is often higher to reduce the user's skin from being in contact with a wet environment for a long time.

In terms of functional design
- Pet potty pads: Usually, antibacterial agents, deodorants, fragrances or attractants are added to help eliminate odors, inhibit bacterial growth, and guide pets to excrete in a fixed position.
- Adult underpads: They pay more attention to antibacterial and anti-allergic properties, as well as leak-proof and comfort designs.
In terms of price
- Pet potty pads: The prices are relatively affordable, especially some ordinary quality pet pee pads, which are suitable for daily mass use.
- Adult underpads: The prices are relatively high, especially for some high-quality adult pee pads with special functions.
