Puppy pee pads
I have several packages of puppy pee pads leftover from when my dog was a puppy. I never used them. But I can tell you that they are made of soft, absorbent materials specifically made to collect pee! And, I bet they can collect something else if I want them to. You can cut one massive puppy pee pad up to make a dozen wipe-sized pieces. These are also not flushable.
