[Q]: I like these stair for my chi, he is only 5 pounds and this stair is easy for him to climb. plus they can easily be carried to my motorhome so he can get on the bed.
[A]: positive

[Q]: I bought these to use around the house instead of carpet slippers as they were making my feet sweat, and after being in work boots all day a bit of fresh air would not go a miss.
[A]: positive

[Q]: Got this because they discontinued the unflavored emulsified MCT oil. This is not a good alternative. Didn't completely dissolve in water and wasn't very creamy like the liquid. Very disappointed in my purchase and will not be buying again.

negative
