Unfortunately, when it comes to fleas, they do not discriminate. Cats of all ages are vulnerable to flea infestations, no matter how many times they have been treated. Fleas can transmit a variety of diseases to your older cat, including tapeworm, hookworm, typhus, and skin infections. To make matters worse, older cats are more vulnerable to developing serious illness from fleas. This is because an older cat has a weaker immune system, and thus has a harder time fighting off diseases. Their skin also takes much longer to recover from skin infections compared to younger cats.
With all this being said, it is imperative that you find the best medicine to protect your older cat from fleas. This is not an easy task, because certain flea medications are not recommended for older cats since they have more at risk immune systems. Below is our list of the best flea medication for older cats.
What is the best flea medication for older cats?
1) Advantage II Flea Treatment
Advantage is one of the most trusted flea medications on the market. It contains 3 layer protection, which means it kills fleas that are in eggs, larvae, and adult fleas. The best part about Advantage is that it starts working in just 12 hours. This is especially good for older cats, because the quicker they can finish the medication, the better.
Frontline is another great flea medication for older cats. While Frontline is a bit more expensive than Advantage, it protects your cat from flea infestation for 30 days. It is also very safe for your cat to take, and is even approved for pregnant cats. Frontline also protects against ticks, which means your older cat will be safe from the deadly Lyme disease.
Cheristin is another flea medication for older cats. It comes in the form of a topical solution that you can easily apply to your cat. We prefer giving older cats flea medication that is in a topical solution instead of pills, because we have found that it is harder to give pills to older cats. Cheristin is also much cheaper than most other flea medications for cats. It is also one of the fastest acting flea medications, as it starts to kill fleas only 30 minutes after it is applied.
