It is not cartilage on the outer legs of cats after walking. Cat cartilage will show symptoms such as deformation of limbs or tail bones, reluctance to walk, lameness, bone pain and other symptoms. The cat's hind limbs may be fractured or the bones are misaligned and healed, resulting in a rounded shape of the hind legs. It is recommended that the owner take the cat to the hospital for examination to see if it can be corrected.

Symptoms of rickets in cats

1. Bone pain. Due to the pain, cats will often keep their forelimbs upright and their hindlimbs sitting.

2. The cat’s legs, feet or other parts of the bones are deformed, with the bones enlarged and distorted.

3. Cats will appear unsteady when walking.

4. As time goes by, cats' rickets will become more and more serious, and they will often adopt a "crouching" posture to relieve pain.

Causes of cat’s hind legs splayed out

1. Congenital hip joint dysplasia.

2. It may be due to unbalanced nutrition in early childhood, such as calcium deficiency, vitamin deficiency, etc., which results in soft bones in dogs and bone deformities.

3. Cats that are kept in cages and often kept in small spaces will basically have weakness in their hind legs. They will be used to sitting for long periods of time, causing joint deformation.

4. Cats often walk in places with low friction, such as ceramic tiles, etc. If they are too slippery, it will lead to skeletal dysplasia in cats and also cause cats to walk awkwardly.

5. The cat’s hind limbs may be fractured or the bones are dislocated and healed after the fracture, resulting in a rounded shape of the hind legs.
