What can cause pain in my cat?

Some types of pain in cats could be caused by an injury, such as a cat bite abscess which are incredibly painful. The cat might show an area of a wound or hair loss and swelling in the area of the injury. Lameness or limping is also a sign of pain. If your cat used to jump a lot but is now staying down on the floor more and not going up in vertical spaces, that can be a sign of arthritic pain. Unfortunately, cancer growing in the body can also cause pain, making the cat seem more reclusive or tired.
