No, the sclera is actually an opaque, white, fibrous layer that protects the eye. It is not a space, it contains collagen and elastic fibers.
Choroid
The sensory anatomy of the eye contains three layers of nervous tissue. Light passes through the two superficial layers, all the way to the deepest layer. From there, the information is processed in the opposite direction, through the middle layer and then to the most superficial layer, where it is collected and then sent to the brain. If the eye were not "inverted", light would strike the most superficial layer and then be processed through the middle layer to the deep layer and then to the brain.
This is the middle layer of the eyeball and it is composed of the choroid, ciliary body and iris.
The sclera in the cat's eye is there to protect the cat's eye. It is the opaque, fibrous, outer layer of the eye. It contains elastic fiber and collagen.
