The bottom material isn't really waterproof. Water resistant is a better description.<br /><br />My elderly, creature-of-habit cat has decided that the bathmat in my ceramic tiled half-bathroom is &#34;the place to pee&#34;. Because of the rubber backing, the bath mat is a pain to keep washing and re-washing, so I began ti use a towel in it's place.  It worked for a little while. My cat found it an acceptable pee surface, and towels are easy to wash. However I became fed up with the pee soaking through the towel and into the grout.  That's why I bought these.<br /><br />Unfortunately the pee soaks through these and into the grout as well. Every morning and evening when I replace the mat with a dry one, the grout underneath is slightly darker ( a tell-tale sign that it is damp)<br /><br />I have 4 and change them every morning and sometimes in the afternoon depending on the smell.  When I first got them about a month ago, about every 1 out of 5 times the pee soaks though to the grout.  I can tell the it has soaked through because the grout is discolored. Now They are a month old and have been washed more than a few times. Over the past week I've noticed that the pee soaks through about every 1 out of 3 times.  I'm not sure if this is because of one months wear and tear, or if maybe my cat is just peeing more.
