My 2 year old cat goes out every day all day and comes back at night. She eats then. Sleeps and back out again. She came home earlier limping and seems very well in herself. She was fine with me inspecting her paw and nothing in her paw. She woke me up playing with my other cat and jumping on and off the bed. And scratching at ther scratch Post. It dosent seem to bother her. Any ideas please or shall I take to vet tomorrow. She's a very active cat and is in great health and been neutered etc.
