If you’re wondering why it’s best to treat and prevent fleas from coming into your cat, here are advantages of using treatment:

Reduce Skin Allergies and Infections

When there are no fleas, or cat eye infection, you and your cat won’t be triggered by any skin allergies or itching. This is important because your cat’s persistent scratching leads to skin infections and a lot of shedding. Plus, the side effects and overall health of your feline friend will deteriorate if you don’t treat it right away!

Prevent Tick-Borne Diseases

When you treat and prevent fleas from coming into your home right away, it reduces the risk of Lime Disease and any other fatal tick-borne diseases that can harm your cat or household. Furthermore, treating the fleas immediately prevents tapeworms, so your cat remains happy and healthy without the irritation!

No Flea Infestations at Home

Last but not the least, you’ll enjoy a flea-free home! After all, no one wants fleas in the house. Not only is it unhealthy, but such a hassle to clean and vacuum to get rid of it. That way, the house and those living in it are free from fleas.

How to Choose the Best Flea Treatment for Cats

These benefits will only work if you choose the right flea treatment suitable for your cat! To help you out, here are some tips and factors to consider:

Type of Treatment

There are different types of treatment to choose from, depending on what works for you and your cat. You ca find oral, powder, or topical solutions. You might also ask,”Can I put neosporin on my cat?”  Select the type that’s easy to apply to your feline friend. Focus on their comfort when applying the treatment to ensure that it’ll work!

Your Cat’s Age

There are treatments that are idea for kittens while others contain ingredients that work best for older or larger cats. Consider your cat’s age and size before purchasing the treatment. Manufacturers would mention the age or size group their cat flea treatments can accommodate.


Last but not the least, your cat flea treatment must be effective! To find out if it works well, you can check out reviews (like these!) and also read up on the list of ingredients the treatment contains. As much as possible, it’s best to find something with gentle ingredients and is easy to apply.

2. Elanco Animal Health Cheristin for Cats Flea Treatment

If you’re in need for something that’s easy to use and apply, then I recommend the Elanco Animal Health flea treatment. This is a topical solution you apply once a month, with it being effective within the day!

What I like about it the most is that it comes with the applicator tip, which makes it easier and gentle to apply to any cat. However, it may not be the most effective on older cats, as there are complaints of senior felines getting sick from it.


  • Extremely useful for kittens and young cats
  • Easy to apply, comes with an applicator
  • Kills fleas for a month and works within half a day


  • Reports of older cats getting sick
  • Some cats don’t like the smell
