Is this project good under pets? How does it stand up to cat urine?

Our 3/8" Sport-Lock Rubber Tiles are great as flooring where pets will be. These tiles are resistant to moisture and will keep the urine on top of the floor for some time. When using this flooring where pets will be, we do recommend using our floor finish and sealer. The floor is somewhat porous, so this will help to fill in those pores. Without the sealer, liquids will not go through the floor but may get in the floor and dry there leaving any salts behind.
