Fold-eared cats can relieve pain by sitting up, lying down and sleeping. They will also adopt a standing position and lift their forelimbs to reduce the pressure of the body weight on the joints. If the owner finds that the cat with folded ears starts to like to lie down to sleep, and will sit upright like a baby when it is doing nothing, it is likely to have a congenital bone genetic disease.

Symptoms of the disease in cats with folded ears

1. Lameness in the hind limbs, frequent lifting of hands, arched back, walking as if walking on stilts, etc. In addition, the cat’s tail appears stubby and its joints are stiff and unable to swing.

2. The bones and joints of the hind limbs develop abnormally, and the foot bones are abnormally bent and shorter than those of normal cats. The bones and joints of the soles of the feet swell, and some cats' toes even become deformed and their claws cannot extend and contract normally.

3. Similar symptoms will also appear on the forelimbs but the degree is milder than those on the hind limbs. Abnormally growing bones and cartilage tissue cause pain to cats and reduce their mobility.
