Cats are masters of disguise when it comes to pain or illnesses. They don't like to show that they're sick or not feeling well, so sometimes you really have to pay attention to discover something is wrong. This can definitely be the case with feline arthritis. They may be hurting more than they are letting on so you may need to pay attention to certain signs.

Watch for things like limping, problems jumping, taking longer to get up and lay down. Some cats change their behavior as well with feline arthritis, for instance they may hide or show aggression more. It's important to give your arthritic cat a warm and soft place to sleep to help make her more comfortable. Also talk to your vet about supplements or pain management.
