Can a tick make my cat ill?

If your cat is bitten by a tick it could be fatal, ticks can live up to several years attached to your cat feeding on its blood (ew, too gory!) and you may not even notice them until they have fed on your cat so much that they become engorged (meaning filled to excess with blood). Ticks can also pass on diseases to your cat that can cause serious health issues and they could also pass on diseases to you and your family.
