3. Catego Fast Acting Flea & Tick Treatment (over 1.5 lbs)

Whether you are looking for a fast relief from a flea menace or you are simply looking for a preventative topical treatment for the upcoming flea season, Catego fast acting flea and tick treatment is a perfect option.

This flea treatment is ideal for cats weighing over 1.5 pounds.

Catego gives quick relief in about 6 hours compared to other brands that take over 12hours. This can help restore sanity to your cat from all the scratching within hours and provide protection for 30 more days.

Catego is an effective solution which deals with fleas in all the stages of their life cycle. It kills flea eggs, larvae, adult fleas, ticks and chewing lice. So you get to kill several birds with one stone.

4. PETARMOR for Cats (over 1.5pounds)

Think of Petarmor as a “store” brand.

It is a good alternative from the popular brands such as Frontline Spot On flea treatment for cats. Even as a generic version, Petarmor helps you protect your furry baby from diseases such as Lyme disease caused by deer ticks.

While the other flea treatments use active ingredients which can kill adult fleas and larvae, the main ingredient used here is fipronil which does not kill larvae and eggs.

You will need to purchase the Petarmor plus which is formulated with the active ingredient methoprene that will help get rid of fleas in all their life cycle stages.

Therefore, if you have a large volume of infestation of fleas, this product may not be your ideal treatment.

In short, consider Petarmor for small volume flea infestation treatment which will not break your bank as compared to purchasing a popular brand which uses the same active ingredient.

From a price point, Petarmor has given a good bargain but the effectiveness of the product as reported by many customers is not impressive. It kills fleas within 24 hours from application.

That is a whole day to see results - not a quick solution.

We picked this flea treatment because it uses a vet quality flea treatment formula. And they have included 3 months supply of topical flea treatments inside the package.

As a tip, for you to get the best results apply this product directly to the dry skin of your cats’ back and between the shoulder blades monthly.


  • Vet quality formula.
  • Cheap price.
  • Kills and prevents adult fleas up to 30 days.
  • It is water resistant.


  • It does not kill fleas eggs and larvae.
  • Can cause burns - watch where you apply it.
