Pros: Sticky tabs on bottom to keep it from slipping, which is helpful since my bunny likes to dig (if there werent sticky tabs, Id rate this a 2 out of 5) Cons: Very thin, absorbency isnt great. My bunny has dermatitis so I change his bedding every 24hrs to keep a dry environment. But even with the pads plus some loose bedding on top, its still pretty damp when I change it the next day. I can see these pads being more beneficial as a backup base layer under some thick bedding, or for animals much smaller than a rabbit (like a hamster, etc).
Ever since my free roam rabbit had decided to claim a new bathroom spot, these have been life savers. Odor control is great and sticky tabs keep it in my litter pans securely. I don't know what I would do without these!!
I have tried them all, and these are absolutely wonderful. I'm using them for my bunny, and the liquid soaks through the top layer keeping your babies dry, and gets trapped between that and the plastic bottom layer. I love them!
