I was wondering what you should look for if a cat's ear is infected. Basically Jake's left ear looked like it was drooping downward a little bit and he wouldn't let me pet him on that spot like he normally does. I'm thinking something might have bitten him or it may be infected or something? I'm not really sure. From what I could tell, there were no ticks or anything on him. Can someone help me out on what it could be? Thanks
