Not as thick as guineadad
I bought this since it was highly reviewed, I'd like to try and support smaller businesses, and it was $5 cheaper than guineadad. My boy loves it, the color is lovely, and it doesn't jam up the washing machine as much as my guineadad liner. However, the pee goes right through and I have to line newspaper beneath it so I'd honestly say if you have male guinea pigs just go with a guineadad liner. It might be ok for girl pigs though.
