My kitchen is old, I'm guessing it's probably been 10 years since the floor was put down (at least 5), and it's peel&stick tile. Now my question is, what does the glue/adhesive smell like? One of my cats decided to use the pantry as her litter box at least once, in the corner. I used Nature's Miracle, but there's still a smell of cat piss, although it seems like it's coming from the corner she didn't use as well. I'm wondering if it's possible it's the adhesive?
