Solids

Solids Lung Cats contains everything that cannot take on the shape of a container easily. Some can be a bit malleable but not enough to take on new shapes.

We can find back some types of Minerals Lung Cats in here, but those ones aren't the "raw" kind, and they usually produce less than their raw counterparts.

Robots Lung Cats are usually in this category, as they require a lot of metals.

Some can also be toxic, and thus need to eat special food to avoid harming living beings in their contact!
