The most effective way to treat lameness is to obtain an accurate diagnosis of what is wrong. If your cat is limping, don’t try to guess what the problem is or wait to see if it gets better on its own. A veterinarian can evaluate your cat by a thorough physical examination; if necessary, laboratory tests can be performed and/or radiographs (x-rays) obtained. Lameness can be caused by many things—infections, fractures, soft tissue injuries, and arthritis, to name a few. Paying attention to signs that your cat is uncomfortable and having your cat evaluated quickly can help prevent smaller problems from becoming bigger ones.
