It’s important to understand that not all cats with joint pain, joint inflammation or mobility issues are suffering from Degenerative Joint Disease (DJD). In fact, DJD is a complex health condition that can only be diagnosed by a professional veterinarian. If you notice your Ragdoll cat is having trouble moving around, playing or getting in and out of his litter box then you should call your vet. Your vet will need to exam your cat to determine that exact cause for its illness. DJD is just one of many joint related conditions. It is a long-term disease that occurs when the cartilage surrounding the muscle joints slowly deteriorates. A full physical exam may be required. The exam will typically reveal a decreased range of motion, stiffness in the legs, deformity in the joints, and swelling or pain in the joints. Only after the exam is complete will your Vet Clinic Rochester, NY be able to make a diagnosis.
