We have these suto delivered.  They are a great healthy sub for potato chips and the snack bags are a perfect size.  Great crunch and we enjoy all the flavors.

Ex Output:
Positive


Ex Input:
This mat is so small, and as others have noted, the "turf" is pointy - so it probably hurts cats' paws (it hurts my knees!)  My cat jumps right over it and I end up with litter kicked up all over the place.  Seems like a good concept, but I would bet it doesn't solve most people's problem of trying to contain the litter.  I just bought an extra large Petmate Litter Catcher that has 4-1/2 stars.  Hopefully, I'll have more success with that!

Ex Output:
Negative


Ex Input:
Salt and Vinegar and BBQ rock!  Plain were OK....Didn't really care for Cheddar.  Nice to start w/a variety pack to find the ones you prefer.

Ex Output:

Positive
