My cat sylah is limping on his front paw I checked it out and from what I could gather there is nothing wrong no pain. I checked all of his legs from the top right down to his paws and he shows no sign of pain. Could he be sick because only the other day he was eating grass and the only thing I could think of he would be eating grass because I fed him some of my food and the piece of meat I gave him was in the fridge for a couple of days but I've eaten it as well and I'm fine. What could be the problem??
