Dang, with 4 of them, I would be broke if I had to change them everytime one of them peed on them. I would probably go through 30 a day. My oldest one was funny at first about having to share a pee pad, but, she has learned now they are to share! The ones I use are great, they can pee about 10 times on one before I have to change it out. The ones from Walmart, i was changing out about 6-7 times a day, compared to 2 or 3 times on these |
