[EX Q]: I have a bichon and I thought this would entertain him for at least 15 minutes, but it didn't. He solved it quickly, within 5 minutes and looked at me as if to say, that's all?
[EX A]: Negative

[EX Q]: I have older mats that have a ribbed surface and work great. These have small stiff points and actually hurt to lean on or kneel on. I can imagine that they hurt my cats paws ad that is why they tend to jump over them when exiting the littler box.
[EX A]: Negative

[EX Q]: i love popchips and this was really a treat to get the variety of flavors and the individual bags were such convenience! Thank you!
[EX A]:
Positive
