My 6 yr old female cat jumped from a tree branch about 5 ft high. She is always jumping up onto ledges or down from them, she jumps very high, always climbing trees, etc. Anyway, her front paw is now swollen and she will not walk on it, she limps all around. She does not seem to be in pain, she still goes up and down the steps and jumps on and off the furniture and beds, going to the food dish etc.
