Can I use one flea treatment for all my cats, big and small?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Longhair | Male | neutered

I have 8 cats. From 2 lbs up to 20 lbs. all over 8 weeks old. Is there a good flea medicine I can use on all cats instead of 3 different kinds ??? How about cheristen ?

You can use Advantage spot on but you will need the two different sizes (for small cats and for large cats), you won't find any reliable and safe treatment that would treat a 2 pound cat as well as a 20 pound cat, there is no such thing.
