Gaseous

Gaseous Lung Cats are for most kinds transparent and hard to spot without them eating a special food coloring them.

They can float even more easily than other Lung Cats, being able to go as high as the clouds for example.

Like the Liquids Lung Cats they can fit in a lot of containers and love taking on new shapes!

Some can be toxic and so they need to eat a special kind of food that will create a protective skin, restraining parts of their body to float freely and thus keeping safe the living beings around or a food that'll neutralize the toxins. They are very understanding of why they must be restrained or have their toxins neutralize and will be happy of keeping the people around safe!
