SmokingCat has randomly started holding his left paw up at various intervals today as if it hurts to be put down, however he's not limping and he's sat down quite happily with his paw on the floor right now. I've tried to have a look and can't see and obvious cuts or swelling, his claws are regularly trimmed but haven't been done in a week or so so I don't think it's that. Any one have any ideas? We have a vets appt tomorrow but I'm worried he's in pain
