Question: 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.

Answer: Negative


Question: The carbonation in this drink was way too much. So much in fact, that it over powered the flavor. (Orange-tangerine is usually very good together).  I expect this from a soda, but not a "healthy" drink. Lose some of that club soda bite and you have one delicious drink. Until then, I'll pass.

Answer: Negative
