One star minus because it smells after 2 days... I don't know if this is an exaggeration... I think changing it every 3 days is reasonable but it can't be done, it doesn't hold up.... I will definitely buy it again because I have found worse ones.

It states that it is 90x180, but it does not mention anywhere that the actual usable area is only 90x60, like most on the market. The rest is just plastic. For humans, it may be normal to be like this, but I bought it for an almost paralyzed kitten that I have, and half of it is essentially useless, while it is also more expensive compared to most available options.
