Q: 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!

A: Negative
****
Q: This 24-pack lasted about a month, and I sampled all of the flavors but only got to eat the barbecue flavor once, as it is my wife's and my favorite. So, I reordered just the barbecue. Great snack for 100 calories. I've purchased the reduced fat Pringles 100-calorie individual packs before, and you get a lot more chips in a Popchips bag than from Pringles.

A: Positive

Q: Smooth coffee with rich, flavorful aroma, along with "low acid" are some of the things I like about this coffee. But the actual taste and the after-taste aren't my cuppa Joe.

A:
Negative
