My cat has always been frisky and lively but just this past weekend she has been sleeping all day and sometimes walks during the night. She won't put pressure on her right leg and won't let you touch it. She let's you touch all of her toes on that leg except for this one that is pink. What should I do?

Cats usually like to clean themselves and you might try observing the cat when they are grooming. See if you can tell just from looking if there is infection or something else going on. Are they cleaning that area more then the rest? Keep an eye out. It may be nothing except a broken or split nail. Or it could be something worse. If not better or swelling develops then take your cat to the vet,

She could have an infection in her toe or she may have fractured her leg.
