Does your cat act like it's not feeling well? From what I've heard, lyme isn't very common in cats, although they can get other things sometimes. My cats have all been bit by ticks and they don't seem to have gotten sick.
One cat has been sick or something ever since I got her when she was a kitten, so I don't think she got something from a tick, or at least not from my yard. I don't let my cats out during tick season anymore.
Bartonella is often what cats carry.
