Fleas are unpleasant and they’re not only uncomfortable for your cat, they usually infect the house and its inhabitants! Ticks are also nasty and so it’s best to use a rub on or tablet deterrent if your cat will take it. Many cats really dislike both tablets, rub on protection or a collar but they do get used to it. If not, maybe find an injectable option. Also, don’t forget to use a brand that also protects them against heartworm as that is often a silent killer. There are plenty of options available to suit all budgets.
