Oh, I’ve just re-read was it because it is the non slip version, not the green backed original version?
To my understanding the non slip is rubber backed so it won’t wick urine down to the absorbent underlayer that you have to put down (for example puppy pads).
You could still use it but it would probably just need to be changed out quicker than the other version. I wouldn’t put it, for example, in a kitchen area as piggies tend to wee and poop where they eat so it would probably get wet quite quickly, or not within a bed area. Perhaps just use it in the middle of a cage where they are more likely to run and play?
