Feline cutaneous asthenia is a rare inheritable skin disease of cats characterised by abnormal elasticity, stretching, and improper healing of the skin. Pendulous wing-like folds of skin form on the cat's back, shoulders and haunches. Even stroking the cat can cause the skin to stretch and tear. A recessive autosomal (non-sex linked) form of feline cutaneous asthenia has been identified in Siamese cats and related breeds. In the homozygous state, it is apparently lethal. Feline cutaneous asthenia is similar to the Ehlers–Danlos syndrome of humans.

Cats with cutaneous asthenia cannot be grasped by the scruff, as this may tear away. Cats may also have slipping joints, as in human Ehlers-Danlos syndrome. Dietary supplements may be needed to promote skin healing and regrowth.
